Incompetence at its peak.

I must say MTN is fundamentally flawed. I have been a loyal customer for more than 6 years. I presently have 2 iPhone 6 contracts ( for me and wife) with them. All of a sudden, I can't call outside SA. Customer care won't pick up. You will be holding for close to an hour and suddenly they will just cut the call. One annoying fact was that they phoned me three months after I app**** for an upgrade online asking if I was still interested. 3 months after. What a shame. Another issue us I suspect they are ripping me off with how they debit me. I called again, no response as usual, I emailed them, no response. This is so pathetic. If they can't help their customers, they might as well take their contracts back. I have seen that they don't respond to complaints and when they do, they ask you to call customer care, the same uncaring customer care you complain about. I demand a response and solution. I can't watch them treat people without respect.
