So disappointed in Cell C service - Cant believe this is how they treat loyal customers

Worst service ever! Upgraded my contract in July 2020. I waited a week for my new device and after phoning the delivery service myself, I had to meet the delivery guy at the mall to collect my phone! I did my sim swap, reloaded all my apps and setup my new device. The next morning the phone was dead! I went to the Cell C shop, but they could not help me as I upgraded online. After sending the phone back and a few calls to them the device was out of box failure. I then had to phone Cell C AGAIN just to find you that there was no stock of the device I upgraded to. They then offered me a cheaper device on the same more expensive contract! I then had to cancel my upgrade and redo the upgrade to be able to select a different device. While I was still waiting for delivery of my new device I started to receive calls from Cell C on other offers I qualify for now that I have upgraded so, I phoned Cell C to ask when my device will be delivered and again the device is out of stock! Cell C did not contact me at all! Cell C don't call you if there is a problem on their side, you have to call them! If you call them and select the option where you want to be you never end up there and they transfer you from one person to another and EVERY TIME you have to give them the all your detail (exactly the same as what you just gave the person you just spoke to). I will be cancelling my contract as soon as I can. I've been a customer for many years, but will never use Cell C again. I will never recommend Cell C to anyone!
