STILL the ongoing (3 weeks now) saga of MTN who sucks

If you want a supplier who doesn't care about their service or customers, who doesn't fulfill promises, sign up with MTN! It has been 3 weeks and still can't make calls, upgrade and can't buy online airtime. I've been marked as a "Bad payer" which is incorrect and they've confirmed that it's their mistake. Their promises to "Fix" this problem as well as the PROMISED (In writing) on their complaints email and after 6 days still NOTHING! Furthermore, there's NO WAY that you can speak to ANYBODY higher up the pecking order as number 135 aren't allowed to escalate this. So you're stuck on square 1. I must however add that the lady helping me at my local MTN Branch (Ladybrand) is doing everything possible, but it seems that even her Regional Manager (Who I managed to speak with), also can't get this sorted. So MTN, your so-called " Helpdesk" causes more problems than getting problems sorted out. My next step will be to contact ICASA. I will research and there may be an ombudsman? Wonder if they will even bother with this.
