MTN Bad Service

I did an upgrade a month ago, received invoice today upgrade was never done. I have to pay more now for something I made the effort to go stand in line for more than two hours before I got assistance and stood another 30+ minutes will consultant assist as he was a trainee. I must now pay more for MTN's negligence.

This is not fair

Today I called MTN the first consultant say I must go back to the shop. Called again the second consultant put the phone in my ear.

Wow some customer service from MTN. if there was an option for no stars, it would be the perfect rating for them NO STARS
