MTN erroneous package

I signed up for 60Gb + 60Gb special on Black Friday over the phone and was promised I will receive my package on the 12 of December. The day came and I was given 100 min, being my previous package which I had been assured was over and done with as I had served my 24 months contract. I then made several calls to MTN and was given a reference 1- ********** 7936 and was told my issue will be escalated and resolved speedily. 2 days later, I was given ONLY 30Gb! Upon calling YET another time I'm told a mistake was made. I asked for data sharing as well and I'm being told there is a network error and my issue will be resolved by 21st December.

My question is how many times must keep calling and how many more mistakes are still going to make before I get the right package I signed up for. Is your staff so *********** that it takes them two weeks to resolve something that seemingly is very simple?
