Useless customer service.

Purchased data on myMTN app with Credit Card. 3 days later I still have no data. Send proof of payment etc. No results whatsoever. They don't care what effect this has on your career. Service is pathetic to say the least! I have to follow up the whole time, they never get back to you. Oh yes, and sorry sir, but even though this is a production issue, MTN IT can't service you on a Saturday, sorry nè! Ons is pateties verby!
