BAD SERVICE-ITS BEEN 3MONTHS AND NO FEEDBACK

My 24 month contract with Telkom Mobile ended in March 2015, a consultant by the name of Nomfundo advised that it has indeed come to an end and that debit orders will stop and a penalty fee will be refunded back to me. I have a telephonic recording confirming the above. I then called the call center as the debit order still went through end of March, they told me that my contract only started in October 2014, which is utter nonsense as i have been paying since 2013. I have sent the voice recording to Sydeny Dube and Hlengiwe who are the supervisors at the call center. Till this day no feedback was given to me. A debit order went through end of April and end of May. I am paying for something that was terminated in March. I called in again and i was put on hold for 40 minutes until i eventually hung up, i sent the same mail to another lady by the name of Hlengiwe Hlatshwayo and still no feedback. PLEASE CAN I BE CONTACTED. I can not continue paying for this service.
