My Account Debited by Cell C now for 5 months with no service from Cell c

I received an SMS from CellC in April offering a cellphone contract (Samsung A33 @ R249.00 pm). I then made an inquiry since I did need a phone. An agent called me, and I told her I needed the phone advertised to me. She said the phone had been discontinued and she immediately offered me a phone that was R50 more We agreed on the colour and so on. To my greatest surprise, I was not sent the phone as agreed upon. Secondly, a day later I received another SMS offering me the same A33 Samsung phone that was initially offered to me. I immediately sent an email to customer service with the 2 questions. This is now in April. Up to this day 01 23, the matter has not been resolved. At some point to pick up the phone and went to another suburb. Thereafter, nothing ever happened. I have written more than 15 emails. Now this week I have been told I should at my own expense phone repairs department to arrange for the phone pick up. I am not sure. The worst part is that Cell C is debiting my account each month for a phone I have never used; it has now been 5 months To me, this is way more than poor service; but an exploitation of a customer. The agent wanted a quick sale and sold me what was available at that moment rather than saying can I wait until the phone is back in stock, then the next thing I get a black phone instead of a colour we agreed on. What kind of a service is this I am honestly so frustrated and made broke by Cell C every month for what I am not using I sent another email asking why should I be making a phone call to the repairs department no one responded to that email from customer service . Oh what an experience with CellC at this age I am truly deverstated and disgusted by the whole thing. I honestly should have kept my Telkom contract and Vodacom
