Terrible Service

I went to take out a contract at MTN last weet @ Somerset Mall branch. Was assisted with friendly service, only to be disappointed again. I took 2 of the EXACT SAME contracts, meaning myself and my mother would get a Hauwei P8 Lite 2017 with R110 airtime per month and 10GB data for the first 3 months, each. My mother had her Vodacom number ported as she did not want a new number. This already took a while and I had to go in again to get the Sim RICA'd. (I was told after the number was ported, everything would start working on the new phone and SIM, which was not the case as I had to go do the RICA first) THEN, my data and airtime got loaded as promised, but my mother only received her airtime. After phoning MTN customer service twice, nothing happened. I contacted the store in Somerset Mall and was told AGAIN that a support call will be logged. Guess what, STILL NOTHING ! This has been going on for a week now. In the meanwhile, my mother's airtime is getting used up because she has no data to use. Why would she only receive airtime, while I received both data and airtime - THIS IS SUPPOSE TO BE TWO OF THE EXACT SAME CONTRACTS ! AND WHY IS NOBODY ABLE TO ASSIST AND FIX THE PROBLEM???!!!!! SUPER DISAPPOINTED IN THE SERVICE I AM RECEIVING AT THE MOMENT AND WILL NOT RECOMMEND MTN TO ANYONE EVER AGAIN.
