Hello everyone, I have been contacted by a company claiming I have not paid an invoice from several years ago. I have a bank statement which I can show them where the transaction is listed with their name and amount. I will be contacting them in the coming days to provide this statement to them, but I am wondering if that is sufficient proof of payment to provide the debt collectors? Can they ask or force me to provide anything further such as a trace from the bank? Not sure who is responsible - I have paid it, they say they never received it.
