Shocking Service / Non-existent Call Centre

I've just had it with MTN. Poor service!!! Non-existent Call Centre!! Renewed 4 contracts between Nov 14 and Dec 14. It's a shambles!!<br> <br> Quite frankly, I feel that MTN dos not value me as a client or my business. I have had and still have numerous billing, airtime, data problems with all 4 new contracts<br> <br> Time to move my business elsewhere!!!
