Do not get a month to month subscription from Metrofibre!!!!!!

I had a month to month fibre subscription with Metrofibre. Cancelled about 3 years ago as I moved. Paid the amount and was under the impression that I have no more dealings with Metrofibre. Almost 3 years later I received the following SMS "Oliver Fox, your MetroFibre account OLI117 has been handed over to Hahn Collections (HC). The outstanding balance of R310.68 can be paid directly to MetroFibre or into FNB ***. For assistance, call ***." I called Hahn collections,and they could not tell me what I was handed over for. I was informed to call Metrofibre. Called and was informed that I need to pay for another month. In 3 years time you could not SMS me informing me of the so called outstanding balance. Send out proper email or SMS accounts. I'm expecting a call from a senior and the account to be rectified.
