MTN cannot fix their mistakes, it's your problem.

I would like to write a review as I am extremelt disappointed, I have worked in a competing company of MTN's so I know the processes. After upgrading to the Mychoice Flexi 500 package on a proper Samsung galaxy device, I cannot use my R500 airtime to convert to data, although it is what is advertised on the site. The contract is not under my name as our entire family's contracts are under one name. MTN cannot fix their problem aas I am not a main member, the main member is a business owner and extremely busy. Now I have to get proof and go through a lot of processes once again because MTN MADE a mistake, I am truely DISGUSTED after so many years of support. Can they not just fix their mistakes??? Why must I be the one going through all the processes and inconveniences ONCE AGAIN???
