hope you can help, My husband had run into some differculty with his mint creditcard and hasn't paid the last two installments last week he rang them and they have said the debt is now with Triton. Then Triton rang him and text and ask for some over the top payment plan they have know written to him asking to clear the loan for £7500 we have had nothing in writing from Mint or the Royal Bank of Scotland so today we sent a recorded letter two all three Triton we asked them to prove they have taken over the debt and the other two to confirm. We are going to try and borrow some money off the family but we can not afford £7500 how do we get the amount down to a reasonable level I have heard that the way Triton do there business is not pleasent and we are in for a bit of a ruff ride thanks for your help
