Vodacom

I have been with Vodacom for many years now and I was using sim only deal getting 20G night data and 20G any time data plus I was able to make phone calls. I was due for upgrade since last year 2023 March. Vodacom agents tried to upgrade/ downgrade my contract for months without any luck. Late last year they tried the upgrade/ downgrade story again and they failed. I couldn't make calls anymore from the number and Vodacom was charging me for phone calls when I called to complain about the bill I was told that the matter will be investigated. In January this year I spoke to another retention agent, she removed the 20G I was getting and gave me Whatsapp tickets for about R35.00 to start if February 2024 while they were trying to figure out wat was wrong with my contract and what was I paying for because I was over charged, she told me that Vodacom will refund me when they are done with the investigation but no one is saying anything to me. Every time I ask them to cancel the contract they convince me to keep the line while they are still trying to fix. My expectation was to see only R35 for Whatsapp ticket but there was R129 on the statement when I call Vodacom to check what was the amount for, they said it was for phone calls and other subscriptions and I couldn't make calls from my number and I did not subscribe to anything
