Telefonica O2 ignored my "prove it" letter. What should i do? i received a letter from Telefonica O2 about a mobile contract the i had no knowledge of. so i rang them. they were nice - very helpful. they said they would sort it out. when i got their next letter i rang them again and again they were great and said they would sort it. however, when i rang them after their next letter they were significantly colder. so i sent them a "prove it" letter. that was all in April / May, since then nothing. i thought it was over. yesterday i received a letter from Wescot Credit Services who seem to think it must be "cool" to show their PO box number and their Post Code but no town or city! it was a "you owe", "pay now or else", etc letter. i'm confused, why have Telefonica O2 simply ignored my "prove it" letter and passed the debt to Wescot? can they do that? please, would should i do?

Hi All Brand new to this forum so sorry if Im in the wrong place, this also might be a little long winded so please bear with me. In 2007-8 I took out 2 x 18 month contracts with 02, one for me, one for the Mrs. In mid 2008 I fell out of work and so could not afford the contract. After a few months of non-payment, both accounts were disconnected and referred to 02s external company. Due to lack of income I had stayed in a few different houses etc while I got back on my feet. I heard nothing from 02 until earlier in 2011. They had passed the debt onto a company called Lowell portfolio, who asked for the full payments of both contracts. The letters were ignored, (shame on me) and I was then contacted by post later in 2011 by a company called Mckenzie hall. In July this year, I was in full time work, and looking to pay off some of my previous owings, so I contacted them. I owed on 2 accounts, totalling, £489.32 and £452.89. The arrangement was to pay the initial "token fee" of £9.32 and £12.89, and then a direct debit of £10 per month just after my payday (agreed for the 1st of the month, paid on 27th) This was confirmed in writing on the 29/07, 1st payment made and the next direct debit due out for 1/09. So far, so good. On around the 5/09 I received a letter for each account saying "broken arrangement - default visit" and basically explaining I had defaulted on my repayment plan. I contacted the agent, and was told that all my details were on system, but the payment was not taken, and could not explain why. Payment plan was confirmed to restart, this time by pre-agreed debit charge, rather than DD and has been successful since. On that conversation, I asked for a call back from a manager, and for them to update my credit record to show the default was incorrect. Now to my problem: I have taken out subscriptions to 2 credit reference agencies: Equifax and Noddle/Call Credit. (Experian apparently have an account for me but i cant get in: another story!) Although Equifax do not show anything for this, Noddle do. My account shows something like this: Lowell: £421 - Updated 14/12/2011 - Status: Default Lowell: £449 - Updated 14/12/2011 - Status: Default I contacted Mckenzie Hall who say this needs to be updated by Lowell as they are the company who sent the action, however, it was Mckenzie hall, who made the mistake. So where do I go from here to have this updated and the false defaults removed, and do I have any legal stance in terms of Mckenzie Hall breaching contract? I have letters and and bank statements to show the arrangement made, and that funds were available. Any help would be greatly appriciated.
