EXTREMELY BAD SERVICE

Our business account was transferred to MTN, since then I have been unable to get hold of anyone at MTN, either via their call centre telephone or e mail. There is never any answer at the telephone numbers. E mails I only get the automated responses with no further contact. I need to upgrade our celphones but have to date not been able to do so. I then tried to move to Cel C, but was blocked by MTN constantly they would send notifications to Cel C that our account is not paid and overdue, so we could not port over, HOWEVER it is paid by debit order. SO I am no closer to getting any assistance from MTN. WELL DONE!!!
