Bull**** Customer service from CELL C

I'm utterly disgusted with the way they do not care about their customers. The only thing they care about is debiting clients every month. So I was helped by a consultant to sign up for a new Connecta 100GB contract. This was on 24 June, I was asked to pay a commitment fee which I have. The sim card for the Connecta never worked, I went to the store more than 3 times. They even did a sim swap. The store consultant advised I must cancel the contract from INCEPTION. When I call to give them instructions they tell me about a 30 days notice. This is *******!!!!! I send emails I make calls no one seems to bother to get back to me. SENZO today took my details to ask his Team leader to call me back. I just want my money back and have the stupid Connecta cancelled!!!!!!!
