I’m not sure if this is even the way to go about this, but heck ill ask the question anyway!My partner recently received a letter in the post from a collections agency stating he owes over £4,000 in unpaid council tax debt. The problem is, he only lived in that property for a maximum of 6 months in 2005 yet they have charged him council tax over 3 years! The letter from the recovery agency was to the attention of himself and also the other person he used to live with at the time but the recovery agency is now saying because they found him, he is responsible for the full debt and have removed the 2nd parties name from the account.The collection agency says we have to contact the local council, while the council are saying the debt was brought by the collection agency and any discussions have to be done with them. We have offered to provide proof that he had left the property after 6months by way of utility bills and payslips to a new address - but the council and collection agency won’t accept this?He is happy to pay the council tax owing for the 6month period he was living there (though he was under the impression it was being paid at the time) but there is no way we can afford to accept this debt of over 4k. Is there any advice you can give me on how to get this sorted?
