A few years ago I signed up with a company called Tax Returned Ltd who do the work for claiming back overpaid tax which they did and charged their hefty fee. All ok.
Fast forward to April 2023 when I tried to do a joint claim with DH but he was having none of it so although I forwarded documents to them no work was done.
In December 2023 DH contacted HMRC to transfer some of his tax allowance to me and they backdated it and sent me a cheque. As I was still registered with Tax Returned at the time HMRC sent them a copy.
Tax Returned want a cut of the money, over £300. I keep contacting them by email to explain it wasn't my claim and I don't owe the fee but now they are threatening legal action.
Not sure what to do.
