VODACOM SERVICE TERRIBLE

I am a very loyal customer with 6 contracts with vodacom and my bill is always paid on time. I was very disappointed when Last Friday the 07 February 2020, i have received a message on my phone that one of my other number has added a recurring 2gig bundle for R135.00 at 16h02. The strange thing is the phone that the sim card was in was off and in my bag. I immediately called vodacom when i got home as i was driving at the time. The consultant insisted that it was done from the phone via USSD. I told her it was impossible as that phone was off and the battery was dead. She said she will log a query and someone will call me between 1 to 3 working days. To date i have not received a call. i have left my main number with the consultant as well but no calls. This is really frustrating as Vodacom is ripping customers off by just added bundles of and we have to fit the bill. Besides this incident. On many occasions we have added whatsapp bundles on our phones and it was not working. Then there are increases on the contracts without informing us, apparently it is on fine print on the terms and conditions, but when the read the terms and conditions for online sales they do not state that. Also i have been with vodacom for over 10 years and when i call in to upgrade or get a new contract there are no discounts or they not even to offer a better deal, whereas if you go to Telkom they are always willing to help. With this service from vodacom, i am rethinking of not renewing my contracts that would be ending.
