Mtn upgrade fails to deliver airtime

I upgraded my contract (now a customer of Mtn for around 10 years) in July at mtn Cresta (not mtn direct) with Bongani. On the first day I tried to upgrade, their biometric system was offline so I had to go back the next day. I took the Huawei p20 with the 'free' Huawei p8 lite for R699 per month. Last month the p20 was credited with the data, minutes and sms's. However, the p8 lite was not. So I went back to the shop to see Bongani, waited for him as he was not in (and the other consultant says he can't help) , and finally after sending an sms to him, he arrives. He checked and said that he loaded the p8lite contract but it was 'kicked out of the system' for some unknown reason. Then he made me fill another set of forms and go through the entire process again! This doesn't seem like he even loaded the p8 lite, as why would I need to fill forms again. Most likely, he neglected those forms initially. He said I would get the airtime the following month. So I decided to wait until this month and check and give Bongani a last chance. Lo and behold, u can guess it,... NO AIRTIME RECEIVED AGAIN!!! Now I'm really furious and it seems like such a futile process to have to go through over and over again. And Bongani is a pathetic excuse for a consultant. Mtn, I don't see any 'brightside' to your appalling service.
