Legal advice please?

Hi,,, im hoping someone can briefly help with what my rights are with a big problem that has arisen with my mobile phone company.. its a bit of a long story so ill try and keep it brief..

about 6 weeks ago i knew my old 18 month contract was comming to an end but i wasnt sure when,, so phoned up to see when i would need to cancel it.... to be met with the news it was up at the end of that month.. at which point the advisor started trying to get me to take a new contract on.... which i said i wasnt sure about as i wanted to look around at other network deals,,,, to cut it short,, he ended up offering me a package to good to resist.. also bear in mind i have 2 account (one my wife uses) and was upgrading both..

2x 4gb N95 nokias on the following tarrif.. ( i agreed to take these after being told 3 had stopped selling the 8GB N95 phones due to so many faulty returns they were making a loss, that was my first choice of phone,,,, but after hearing that i accepted the standard 4gb version, this was a complete lie by the way.. every operative i spoke to after was happy to sell me the 8GB phone when i phoned up pretending to be a new customer....))


300 xnet mins
300 3 to 3 mins
25 photo messages
25 video mins
150 txts
£5 free downloads from the three website
30meg internet usage
£10 loyalty discount off each account (should be £25 so down to £15)
plus if i signed up on THAT day... a further 200 texts would be added free to each account

good eh?? i thought so too and took the deal

phones come... no 4gb memory cards as told.. so i phoned up to see where they were,,, only to be told that none were being provided... i explained i had been told i was recieving 2x 4gb phones... which i obviously hadnent.. they fobbed me off as a misunderstanding on my part... so i asked what else i had "misunderstood" about the deal oferd me...
Turns out i had no 30meg free internet a month, and no 300 3 to 3 mins... which annoyed me as the internet was 1 of the main reasons i had took the deal.. and had STRESSED to the salesman about it definatly being part of the deal... definitly no misunderstanding.. so after being passed from pillar to post.. they refused to find out the truth saying thet i couldent prove anything, and when i asked for them to listen to the voice recordding of the call they said they couldent as they were taken at random, and had no way to check!

i took it as high as i could.. but gave up after even head office refused to do anything... and just accepted the fact i had been lied to, but still had a pretty good deal so i would swallow my anger and accept it..

a few days later i get a letter confirming my new tarrif.. clearly stating that it would ne the VTT tarif 500, at £25 a month... with a £10 loyalty return making it £15 every month... but no mention of the 200 free texts... so i phoned up again... 3 differnt people i phoned to make absolutly sure i had the same story from each... and they all said yup the 200 txts were there and would start when the new contract commenced at the end of the month..

so the new contract stars and i get my first bill for my phone.... as expected... £15, but no txts,,,,,, another phone call... they dont know why there not added but will do it manualy now... they will be added from the next month..

now where it goes really bad... i get my second bill a day or so later...
the 200 free texts are there... but the bill is for £25.. not £15 as i was told,, and as my letter stated.. so another phone call ensues..

Now there saying that the tarrif is £25, the texts are another £10 bolt on... and there refunding me £10 loyalty to only cover the cost of the 200 texts bolt on!

So even though i have a letter STATING my tarrif is £25... with a 10 quid loyalty discount making it £15 a month... there refusing to honor it.... telling me i have to now pay £25... i even said i dont need the 200 extra texts.. ( i sent 9 last month) and i just want what the letter states... the standard tarrif with nothing "free" or "added" , and ill pay the £15 a month but they refuse to do it... they even admitted that the letter they sent is wrong... and what the advisor told me is wrong... but still refuse to budge!!

What initialy turned into a great upgrade deal... has turned into a nitemare... and im expected to foot an extra £360 over the next 18 months to cover THEIR mistakes?? im so angry !

surely if i have written proof of what my contract is they cant refuse to honor it saying the letter is wrong ????

Frankly im amazed at the level of incompetence.... as far as Three are concerned.. there sales team can offer customers the moon to get them to sign new contracts,,,,,, then just lie and say these things were never offerd.. or up the price of the tarrif,, and i as a customer have absolutly no way of proving what was promised me... even when im holding a letter from them!!

please can anyone tell me my rights as im not letting this one go without a hell of a fight...

thanks for bothering to read all this,,, i know it goes on a bit ;/
