Worst service provider ever!!

So here I am, a month later, and mtn has given me the middle finger. My ****** data still hasn't been replaced, I didn't even get my new recharge so I can't check to see if these useless idiots have done anything about the night time connectivity. I don't know what to do anymore - I think you should just get someone to call me and cancel this contract and you can shove it up your ***!!! A company like yours shouldn't be allowed to exist and all your useless good-for-nothing staff should just drop dead - it's not as if they mean anything anyway. Pathetic!!!! Close your damn doors!!!!!!!
