Yes I have the account number and sort code. It was with the same bank that I was supposed to pay into if I paid by bank transfer and in the same city, although I doubt the company still has this account open.

Yes it was paid into an account

I have got the cheque and been to the bank, it was cashed on 29th July 2009 (and I dont see how it could have got into the wrong hands and been cashed by someone else). The DCA has written to me again saying I will go to court. Who do I contact now? The DCA or the company that overpaid me? As the overpayment occured 4 years ago the numbers on the original letters dont work anymore and I doubt the same people still work there. Should I send a copy of the cheque to the DCA? I have a feeling they will just ignore it and take me to court anyway and waste more of my time and money than it already has.

I don't think so. I was overpaid in Sept 2008, I got 3 letters, 3 days after the 3rd one I sent the cheque which I got from my ISA. I asked for confirmation but never received it. I heard nothing for 3 years until this. I took photocopies of all the letters I recieved and the letter and cheque that I sent to them.

The thing is im starting to doubt whether they received it. It wasnt a normal cheque I dont think. I cant really remember - I took it out my ISA and then sent them the cheque but I think the money came out the moment I got the cheque written in the bank. I never got confirmation that they had got my letter+cheque even though I asked for it (I thought at the time why should I bother as I know they will just come up with some crap like this at some point) I dont know, I was only 18 at the time. Either way it makes me want to scream

Just got a letter from 'Sinclair Goldberg Price Limited' saying: "FINAL DEMAND WE NOW OFFER YOU A FINAL OPPORTUNITY TO MAKE PAYMENT OF £2306.00 OVERDUE TO OUR CLIENT ****** FOR YOUR SALARY OVERPAYMENT THIS MUST BE SENT DIRECTLY WITHIN 7 DAYS FAILURE TO DO SO WILL RESULT IN LEGAL ACTION other small print" First of all this overpayment occured in 2008, and they overpayed me 1.9k, not £2.3k Secondly i already gave them the money back in 2009, I have photocopies of the cheque I sent and the money came out of my ISA account. Thirdly I dont have 2.3k to pay back anyway What do I do? I'm not even going to respond to the DCA, I might contact my old employer, what should I do?
