faulty 02 phone

belfastpaul

Ive just had my 02 mini s xda phone returned to me after having returned it to 02 shop as it deveolped a problem (screen fault)almost 11 months into contract,, in fairness they did give me a loan phone but as you can imagine it was very basic with limited features,, got phone returned to me 3 days ago with letter saying "that fault had identified and the necessary repairs had been successfully completed"
also they had taken the opportunity of installing the latest 02 approved manafacturers software which corrects any known faults in original software,,
couldnt believe it when i inserted my sim card and the phone wasnt even starting up,, it would try but then eventually after about 3 mins would just turn it off (battery was fully charged),
ive since been on to phone to 02 informing them of fault, and venting my fustration as im paying for a service which im unable to use to its full potential ie email, internet camera bluetooth etc,
I've mentioned to them that im due for an upgrade in just over 1 months time and am gonna renew my contract (its a staff contract, work p/t in dixons tax free), they insisted that they could not upgrade my phone now and would have to be returned to store to be fixed again,, seems a bit silly as when i eventually get it back i'll be getting shot of it,,,
Anyone got any ideas which way to approach it or will i just have to put up with it an wait,
Cheers
