MTN Bad service and DISHONESTY

I got my MTN Sim contract and activated on the 22nd October 2025. My package is 50GB for R200 a month. Now, when I activated my SIM I oy got 15GB ( which was never discussed with me). I enquired about it, was told I was provisioned pro rate. Which means I was provisioned with what was left for the month. The full package was said to be provisioned on the 27th of October. Come 27, no data. I enquired again, they told me stories that I'll only get my full package on the 1st. I'm so disappointed in MTN. Such a big network provider in South Africa!
