Hi I am having problems with the tax credits compliance team, my xp and I had a joint claim until Feb 2012 when we split up, opened a single bank account and moved into my mothers house ( which might seem strange but she is disabled and he is the named driver on her car so he needed to be whithin 3 miles of her house). Anyhow I got a phone call from tc in Preston in January of this year asking why I had not contacted them about the letter they sent me I didn't get any letter n told them this, it was then they informed me they where investigating my single claim status and I was asked send proof that my xp was not living at the same address. I asked what info they needed and sent a copy of his driving licence and a letter from his dentist which they said in a letter to me they didn't receive I offered to send them letters from my xp and my mum and other people and was told they couldn't accept this as it is third party info and could be written by anyone. I asked them about the info they had and they said my xp opened a bank account in February 2012 in my address I explained that because he had no proof of address at the time of openining account he had to use previous 1 and the other aspect they had was voters role I asked how this was possible as only me and my som where on the voters role when they checked the date of birth it was my sons. I asked again what info they held and was told in no uncertain terms that they could not give me info as that would breech the other persons financial data act. All the bills are in my name and I sent a copy of bank statements for the year they are querying and a copy of electricity bill, tv licence, and his wage slip, dentist letter, and driving licence again. They have now informed me I need to repay £1414 for 2011-2012 and £8544 for 2012-2013. I am completely stumped as I am now on ESA as I have a serious heart condition and had an ICD fitted last year. Any help would be much appreciated
