Edgars is *********** and **********

My father passed on in January. He had an account with edgars which had an account protection plan. This means that upon death the outstanding balance on his account would be settled and the account would be closed afterwards. Fast forward to today, we receive a letter saying that the account has been handed over to MBD for collection. This is PLAIN CRAZY and RIDICULOUS. Why should we pay the account of it had account protection? I'll keep fighting this
