*****, *****ing money

I went to Mtn Northgate mall store to get WiFi 2 October 2021, the sales consultant at Mtn said I had coverage, I didn’t have internet for two weeks she said they need to activate it???? Then to say that I don’t have coverage. So I took it back and canceled. Now they debiting my account and debiting more then what the contract I signed for. I spoken to the store they say contact retention now Retrenton doesn’t answer their calls I’ve tried emailing and they say go to store but no one is helping me???
