Pathetic Service, false advertising

I have had the worst experience in dealing with *********** staff from Cell C for three weeks. With my upgrade due, I went into one of the stores to decide on a phone. After choosing the iPhone 11 in purple, I was told that they did not keep stock at the store and that they would need to order the phone which would arrive the next week. A week later I called the store and was told they still did not have stock. I was advised to contact the call center where I spoke to a rude and impatient Akshay Singh who at the end of the call said he would be placing an order. Today, three weeks later, I received a call offering me a new contract and I told the consultant that I'm actually waiting for feedback on the phone I ordered. After being transferred to three different consultants, I was told that no one had placed the order for the phone and that they were given instructions to not place orders for this year. I was then told that even if they did place an order, the stock they receive next week would go to those who ordered weeks ago. This is despite the fact that I DID order weeks ago but their staff don't know how to do their jobs. The staff at stores seem to think they will be receiving stock but according to the call center, there will be no new stock. Cell C are advertising products that they don't have and they are messing up. When I brought this issue to their attention on Facebook, another staff said that I should try and source the phone from elsewhere where they could deliver faster. I've had a contract with this service provider for six years and I spend more than R2000 a month with them so their service and response and been pathetic. If they are having issues with their supply then they should stop advertising the products. Maybe they can use some of the money they save from advertising to pay for their staff to be trained. Their social media person said their team would assist but did not ask my contact details. I guess I should wait for that too. Also, I'm more than happy to cancel my contract, buy me out for the remaining months as you cannot provide a service. Vodacom said they could get the phone in 3-4 days and they are cheaper.
