MTN Wonderboom Junction Bad Service

After checking my upgrade date on the mtn app, and receiving a notification that i can upgrade my mtn contract in April 2021, I proccedded to go to MTN Wonderboom Junction in Pretoria, the person who assisted me proccedded to tell me that I can not upgrade, and that I can only upgrade in July as their policy has changed. I told him I received notification that I can upgrage. He just said that if I want to upgrade I would have to pay R700 for the remaining months on the current contract. I then left the store. When I got home, I called MTN customercare, and they confirmed that I can do an upgrage, as I am in the 3 month period leading up to my expirey date of my current contract. I am highly upset about the createment I have received from MTN Wonderboom Junction, as i have always gone their in the past. This treatment was unacceptable, and I waisted my time. It just feels like the person (I failed to get his name) did not want to assist me. I will not be returning to that shop in the future
