Mtn worst customer service ever

Hi

I took up the Black Friday data sim contract and it was delivered to me on the 5th December. I have called the Mtn call center more than 8 times trying to activate it but kept being given different reference numbers. Next I was debited yet upon taking the contract I was told first debit would be in January. At this point I just need help canceling this contract I have tried calling the cancellations department but no one ever answers , also tried going in store but still got no assistance instead was told Mtn has enough customers and does not care .

Can someone please assist me , I just need this router and sim picked up , the contract cancelled and my money back . We a few days left to the month I’m stuck with 50gigs that was never activated.

Please help me
