****ed off for the second time

I am getting extremely ****ed off with MetroFibre. On my previous review MetroFibre insured me that my account was canceled after I have tried to get in contact with them for more than a month due to their client portal not working. In the week I received an invoice for R1300 stating my account is overdue. This invoice is for an OPENING of an account. I don't want an account with you. Please take this invoice off of my name immediately
