italk telecom cold calling problem

I am asking on behalf of my Mum, and no intended disrespect to my Mum but she can be a bit two sandwiches short of a picnic at times. She was called by italk telecom and asked to provide details for direct debit which she gave. I think she was under the impression she was talking to BT and that she was providing card details to BT. They gave her the number 08453734290 calling this the customer services number if she decided to cancel within 14 days, which she has done. These are the only details I can discern as she won't elaborate further.

I have concerns if they decide to forget about the cancellation request. Namely that she has only just signed up to BT so still within the 12 months and if the contract is changed over to another company this will no doubt incurr a charge from BT. Also the company seems to have a fondness for 24 month self-renewing contracts and high call charges.

Also, I am sure it is illegal for them to have called her in the first place as she is on TPS? I wonder if these rogues use TPS as a database to call. I might put in a complaint on her behalf http://complaints.tpsonline.org.uk/Consumer/

Some keywords so hopefully google will pick up and direct anyone else with issues with this company here. 08453734290 0845 3734290 0845 373 4290 italktelecom.co.uk italktelecom
