MTN run like our country 's SOE's...useless

Firstly we did the *1**# to check upgrade eligibility. It cambe back as 10.02.2022. One week later on the 19.02.2022 we went to MTN cape gate to do the upgrade for and decided on the 2x nova 9's( to give one to my daugter) the very friendly lady whent to check stock qnd came back with the last 2 in stock(obviously we felt lucky) after 10min the upgrade was declined as the previous device is not yet paid off. So Valuabletime and Diesel wasted. We where told to come back 1.03.2022but my fiance did online upgrade on my fiance's phone about a week ago. Now I need to be present to answer her phone for authorization. It cant be done because I leave the house before 6am and get back home after 6pm, which is out of the office hours. I get that it is for security but exceptions or alternatives should be made. The other thing that really works me up is every time I make a call a sms is sent only saying..."you will recieve 0% Discount" PLEASE stop that. Ive had both contracts with MTN for about 10 years now. This will be my last upgrade. 2 years from now I WILL change my service provider. Your service has gone down the toilet.
