Again BAD service from MTN

On Saturday morning I went to MTN Clearwater to upgrade my contract. Apparently they did not have the watch that was advertised with the P40 lite and I was told that they would get an update on Monday 6 July 2020 and I would be contacted. That never happened as usual. On Monday I then went to the bigger MTN store to find out if they could help me. I wanted an upgrade and a complete ITC check was done on my profile, unsure why. This time I was told that he could not complete the application and he would phone me back on Tuesday, This I could not understand. Again I was told that he would get back to me on Tuesday so that he could complete the application??? Does MTN not want me as a customer?
