Bad service from vodacom!!!

Looks like vodacom wants to become a ***** company!!! Im really getting frustrated with them. We are struggeling for more than 2 years now. I don't know what is the problem we never struggeled with them before. But it seems like they wants to take our money and we must just be okay with it. Last year vodacom rewards phoned us we got 2 lines but we were not happy as they gave us wrong information so we phoned in and they didn't want to cancel so we used hello peter after a few months the things was sorted. Or this is what vodacom told us. They **** to us. It was never the case. They stopped 1 line but not the other line. I am paying from july 2020 on a line we don't even have anymore. So i wrote to hello peter after phoning vodacom and they said we must pay a lot to cancel the contract (i'm not paying a cent) (in fact they owe me, and i want my money). Vodacom phoned me and said they can't see the problem. i must open a ***** case so they can investigate. It's not ***** it's vodacom that wants to do *****. Why didn't they stop the lines. So after i got cross and dropped the phone i phoned back vodacom self and they explain that the 1 line was never stopped as it was a router. So now she said i must send the router back so they can give my money. I am not happy as i said i did send the router back long tie ago. Please help me sort this out i'm so fed up with vodacom. They said it's sorted now but it's not. I want my money back and i want them to stop the line. I just feel like vodacom is giving us bad service for the last 2 or 3 years. I told them i don't want to work with them anymore then they promised me good service so i renewed 2 lines 3rd line renewing now and opened 1 new line. And now this again. I'm so fed up with this. Please help me sort this out!!!
