Cell c miss-selling phone contracts

I have placed an order over the phone for a upgrade handset deal on the 30 April 2021, I followed up on the account on the 7th and the agent advised me I was upgraded to a phone that they don't have stock of and there is 1300 orders outstanding. Now is the 18th of May and I still don't have the phone, so I went to the store and was advised that this can be reversed so I can get it at the store and they have stock. Now it's taking over 48 hours to do my reversal to an order I was missed sold and waited for nothing. I phone the cancellations team to check my reversal, guess what I can't speak to a anger about it cause from the all the team there is 1 manager and she refused to speak to me saying she is on a call, then a meeting and the a video call. Wow what **** service I have been given and I'm with you'll for over 6 years.
