Terrible service

I have been struggeling for exactly a month to date to get hold of MTN, when i go into the branch they tell me only the call centre can help me...the call centre have dropped my call 18 times in a matter of a few hours, nevermind not answering and all the other days this has happened to me. They changed both contracts on my name by themselves without consulting with me, they have mistakenly taken R130 of my R200 every month for 3 downloaded songs and i'm absolutely sick of this. I used to reccomend MTN to friends and family. This will NEVER happen again. Unfortunetly im bound by contract other wise i would've given my phone back and pay any amount of money to get out of tje arrangement!!!
