I just received a final demand letter saying that I owe £51.40, however I haven’t received any previous demands and when I log into my account it states that I only owe £4.06, which I paid immediately. I tried asking the live chat for help, however it couldn’t understand my query. Firstly issuing a threatening final demand letter without any previous correspondence is wrong, secondly issuing a demand letter for a completely different amount to what’s outstanding on my account is also wrong, both are examples of really poor customer service.
