Billing old contract and New for six months

I am writing in hope that maybe a bit of publicity will get Telkom to react.<br> <br> It's been almost 6 months since I change my Wireless Internet (LTE) from a 15 Gigabyte Bundle to an Uncapped Bundle. I did it all on-line and over the phone. The representative assured me that the old contract would be migrated to the new one. It has now been almost 6 months and I'm still being charged double. I have waited hours on the call centre line and often got through to someone who always escalates my claim. After 2 months of that I decided to ask for a supervisor. Every time I need to speak to one they are either busy or in a meeting. As of January I managed to get hold of a Supervisor. She was helpful at first and kept me updated via email. And then... Still nothing it's now march and I just received a statement saying I will again pay double. And i don't even receive a response even though i have received read receipts!<br>
