MTN 2 Mall of Africa bad service by Diana

I app**** for a cell phone contract at MTN 2 Mall of Africa on the 10. 04.2019 assisted by a lady by the name of Dianna she then told me to come the following day to collect my Huawei p8 Iite I told her I will be a it late, I got there around 19:40 she the told me she is busy cashing up I should come the filling day I explained her that am coming all a way from Pretoria... She told me there is nothing she can do I must just come the following day.... No one bothers to help me at the branch they all cash up while am sitting there to collect my phone.... I was so disappointed by their service. With anger I told her to cancel it immediately. MTN 2 service is so bad I will never recommend anyone to buy a phone from MTN store, Diana service was pathetic, they even close doors at 19:50. I waisted my petrol to drive there... I was so so disapointed
