Bad company, obviously

If I could give less than 1 star, I would. For more than a year I've been battling with Vodacom for messing up the contract between myself and one of my dependents with another number. There was an initial error that made it impossible for my number to make calls. I was told the data plan I had can't make calls, and I said well, why did you put me on that data plan? (My previous one, also data plan, COULD make calls). They didn't know, someone somewhere made an error. Then, for more than a year, I was charged the extra amount for one of the numbers (near R7000 instead of R300). In the meantime, I cancelled that contract because I went overseas... But lo and behold, even though I was assured everything was sorted in person at a vodacom store, it wasn't cancelled. When I came back months later (still being debited each month of course, no matter how much custromer care centre outreaches I made), I went to a shop again, finally got them to acknowledge it was a mistake (at first they said I need to pay THEM because my SA account ran out of money for these debits) and off I went again. Obviously nothing has changed, and I'm still being billed. It feels like such a ****. They have every email, every phone call recorded... Yet dump it back on me with a solid gaslighting experience every time i try to reach out. Now they've started debiting both me and the other dependent. So yeah, stay far away.
