Poor service & Lack of care

I contacted MTN on Friday as i am being charged for MTN to MTN calls yet i have a contract with 10 000 MTN minutes which i am paying for. I was told that it would be resolved in 24 hours. since then i havent heard anything, no refund, no call or resolution. I then called in on Saturday as the MTN reception in Fourways is absolutely pathetic, i spoke to 3 agents and a a manager Mhlotsi who was rude, arrogant and down right DOM! he passed me from pillar to post and could offer no real customer care or concern, I asked to speak to a manager who was to call me yesterday but since then i never got a call. I even emailed their executive complaints add and no response. MTN you SUCK, Your products SUCK and your staff SUCK, why must i pay for a service that i cannot use?
