MTN is really the worst!!!!!!

This is the 2nd time i had to write a review, thats the only way someone helps! The whatsapp chat lines to assist on mtn - doesnt work, they ignore you. The lydenburg number listed, they ignore you on whatsapp, they ignore the phonecalls. Then I app**** for a 2nd line, they dont call back to say if it was approved or declined (this was online), i called to find out if i can do an early upgrade knowing there is a fee involved, they said no, when i quoted wat the mtn website states as yes you can, then they said "oh okay let me transfer to someone that can help you" no one helped. Went to the Lydenburg branch to do the early upgrade, promised a phone call back, no call received. phoned them, no answer! this is the worst cellphone network and i will rather cancel my contract than upgrade it!
