Horrible Service from Vodacom- ****

I was on a Vodacom contract Red Flexi 200 until January 2024 when they called me to say this is being phased out and will be moving to Red Flexi 260 with no extra cost to me. However, end in February my bill was R60 more and I’ve been calling to find out what’s happening with no assistance, the matter keeps being escalated and no results or feedback. In March my bill was up by R80 and the statement read Red Flexi 280, my bill keeps increasing month on month, I amount still not getting any feedback from Vodacom. I want to cancel this contract. Horrible service my query number is ***
