MTN Contract application cancellation horror

On Monday 24/08/2020I went to the Centurion branch MTN Direct to apply for a phone and they did not have the 5g model of the note 20 plus, but I ended up settling for the 4g model. The sales person then could not finish the application as there was a problem with her system and it was already 30 minutes past closing, I then opt to cancel the application. The next day I call and find a branch with the 5g model in stock and I when they process my application they find that the Centurion branch ordered a phone for me from the warehouse. I went back to Centurion and it's been since tuesday 11h00 I've been waiting for that application to be cancelled. From the beginning the Store Manager gave me bad attitude, interrupting me while I speak with her on the phone telling me why did I go to the other branch. Unfortunately my data contract is only expiring in April so I cannot move to Vodacom as I make use of datashare and dont want to carry a router around. It's my own choice where I want to make my application and it feels like now I am being forced to end up accepting the phone they ordered for me.
