Absolute disgrace

<p>I have a sheet street account that has been settled for months already and I think the account is closed already but apparently it is still picking up arrear payments on my name. I tried 3 times calling the customer services but they keep telling me the system is offline and if I want to leave a message they put down the phone. That is so rude and unacceptable behaviour. All I need is a letter of proof that my account is not in arrears and have no balance at all and probably closed. If I don't receive this letter before 5 pm today I'm going to the name and shame sheet street on all social media. Rude rude rude </p>
