Account was cancelled 6months but still get accoun

My Telkom account was cancelled 7 months ago (A***1) every month i go into the Telkom office at Bayside Tableview Cape Town and every month i get told that its due to the Telkom backlog that the account is not closed as yet. for the last month i get phone calls from an external rude VVM company saying my account was handed over because of it being in arrears. After receiving a apology letter from Olga from Telkom i still get the company saying my account was handed over. This is putting me in a back credit rating light and it is unexceptional. i do not know what to do anymore. this is not on. I do know that Telkom does not provide a service but why is it that the client must be in a bad credit rating state due to telkoms backlog???
