A FED UP CUSTOMER

I HAVE A PROBLEM WITH TELKOM INSURANCE, I CANCELLED MY INSURANCE 3 MONTHS BACK AND THEY STILL DEBITING ME, I CALLED THEM NUMEROUS TIMES AND THEY ALWAYS TRANSFERRING ME AND CANNOT ASSIST ME. I SENT EMAILS, NO REPLY. THEY CONFIRM THAT MY INSURANCE IS CANCELLED BUT YET THEY SENT ME INVOICES AND DEDUCT EVERY MONTH. I CANT TAKE IT ANYMORE. I AM IN A PROCESS OF OPENING A CASE. I AM FED UP.
