Worst. Service. Ever.

Vodacom has the absolute worst service that I've ever experienced. In May 2020 I went for an upgrade as well as for my contract to be transferred from my dad's name to my own. Ever since I've been at Vodacom 4 times, each time again with all the paperwork required by them to transfer my contract, and it still has not been done. No one can help me or give me an answer about why or what I should do, their answer is either to call customer service or to go in-store with all the paperwork and start the process again. And on top of that, for some reason, I have an account of R3500 which does not make sense because I pay my bill every month, but of course, no one can give me an answer because my contract is still in my dad's name which I also cannot change because they can't help me??
