SHOCKING SERVICE FROM VODACOM

Shocking SHOCKING service from Vodacom! I have been a customer for years. When I called on 26 January 2021 to cancel two contracts of mine, they cancelled the one and not the other. They then proceeded to bill me for Feb 2021 and March 2021 for the uncancelled contract - even though I've called multiple times, and now refuse to do anything about the cancellation saying I'M IN ARREARS!! I'm only in arrears because they billed me for the line when they weren't supposed to. When I ask to speak to a supervisor I'm being **** to saying that they're not available, they don't take calls, I can't get reference numbers for my calls...the list goes on. I WILL NEVER DO BUSINESS WITH VODACOM AGAIN.
