Poor Service from Telkom

In May 2018 the telephone lines were ******. I continued to pay my account in the hope that my line would be restored. When it became evident that my line would not be restored, I contacted Telkom to request a refund. This took many months but I was eventually I received the refund. The monthly accounts for the discontinued service however continued. On the 29 May I received an SMS to call P&P Attorneys regarding my outstanding Telkom Account Ref 37M056112. I requested to be advised what the outstanding amount was and for service and the period this service was provided for. Their contact person is Caleb Ryce. After I asked for the above information, Caleb sent me an email today that the file on me is now closed andnoto refrain from calling their office in the future? Telkom apparently appointed this firm of Attorneys to hassle me. Telkom WHAT IS THE PROBLEM WITH MY ACCOUNT, and why was I handed over to the attorneys?
