Cancelled account still incurring charges and I'm FED UP!

<p>Earlier this year I phoned Altech Netstar to settle my account in order to completely cancel the account. I made arrangements with one of their consultants for the settlement amount to be debited off my account on 15 July 2016 and for the account to be closed as from that day. ON 15 july the money was debited from my account. On 5 August I called once again to confirm my account with them was settled and closed, (believe me when I say I was insistent with the consultant about whether the account was truly cancelled, closed, finished!) The consultant affirmed that my account was paid in full and that he has closed it. ALTECH Netstar did not send me any form of proof of payment (although I have the bank statement to prove the settlement was debited off of my bank account). Then, on 21 September ALTECH NeNetstar has the AUDACITY to e-mail me another statement! This time the bill came to R122.20 for an account I ****ING CANCELLED! I DO NOT OWE THEM THE MONEY FOR THEIR INCOMPETENCE! </p> <p>I calmly called them on the 21st of September to query this bill and the gentleman I spoke to, Fabian Phillips, had no clue about any settlement I had paid two months prior. He's requested the call records (yeah right!) and is waiting on those to confirm that my cancelled account is actually settled. </p> <p>I TELL YOU WHAT ALTECH NETSTAR, YOU LOST ME AS A CLIENT BECAUSE OF YOUR *********** STAFF, AND NOW WITH MY NEW CAR OR ANY OTHER CAR I PURCHASE IN THE FUTURE WILL NEVER HAVE AN ALTECH NETSTAR TRACKER IN IT! AND ANY INSURANCE COMPANY ASSOCIATED WITH YOU WILL NEVER HAVE MY BUSINESS EITHER!! I WANT THIS SORTED OUT. YOU HAVE WASTED ENOUGH OF MY TIME AND MONEY WITH PHONE CALLS (ALL MADE BY ME) . </p> <p> </p>
