MTN - WORST SERVICE PROVIDER IN SA

THE WORST SERVICE PROVIDER!!! I have been asking for 3 months for my debit orders to be changed and still every month it goes off on the wrong days. Every single time the manager says the consultant didn't log it?! So not only are their consultants not trained to do their jobs but now they refuse to pay me back for banking charges that occurred from THEIR incompetence????? The cherry on the cake is that they still have the audacity to terminate my service until I make a payment!! I am absolutely disappointing and enraged by this excuse of a service provider!!!
