Telkoms day light *******

I called telkom for an amount due for payment in April due to the fact that my debit order was unpaid and I was given an amount of R306.74 which I paid via eft. I also cancelled my contract with telkom in the month of April. I received a urgent payment letter from nudebts on the 28 May and it was Addressed to a Mr and I am a Mrs so I ignored it not thinking anything because I was under the impression that my account was up to date and cancelled but after receiving a final notice of demand on 31 May, I decided to call telkom and I was told that my account is in ARREARS and has been handed over. To my knowledge I have paid my account in full. I honestly believe that now that my contract has come to an end that telkom are trying to attach costs that never existed prior. I received no form of communication whatsoever from telkom to say that my account is in arrears or that it was about to be handed over until I started receiving emails from Nudebt debt collectors which I feel is utter nonsense and very disappointing as a loyal customer. When I called the call center and spoke to an agent she did not even log a case about this. VERY DISAPPOINTED in how telkom does business.
