Bad Service Mtn

Hi, I am not happy with mtn! We've been phoning all week and got through at last. We've been asking them to give my hubby a good deal as he is due for an upgrade. I asked them for something similar to my contract *** with 150 free minutes and 11 gig data for +-R300. We spoke to Vumelelo. My husband André van der Westhuizen spoke to her. And they discussed a Galaxy A32 with R150 minutes and 2 gig of data. She said she would get back to him either yesterday or this morning. But no phone call. :( We are not impressed. He wants to cancel both contracts, but once again we need to phone. I have screen shots for holding on for more than 30minutes each time. Really? Can mtn phone us back urgently? We have been your customers for many many years!!!
