Hi Keeley.

I too cancelled my direct debit and went through Trading Standards and Ofcom, they were both really of little help.

After a few months passed having cancelled the Direct Debit I received a letter from a 'telecoms debt collection agency'.
Don't be fooled, these are not a stand alone company, but are actually working through 3. Basically their contact number traces back to a 3 call centre, so it seems to me they are posing as this debt collection agency, when really it is just 3 pushing for your payments.
Although, dont hold me to that, I do not know what kind of powers they have (i.e. giving your future credit rating a black mark etc).

As you have probably read in previous posts, I contacted the Mirror investigators who I believe are investigating them at the moment (although I have heard nothing back from then since last contact around a month ago.)

Keep in touch with your progress (if you have any!) and let us know what your Trading Standards officer says.
Thanks

Mark
