Mtn Non existant Customer Service

Due to our company going through some issues I have not been paid on time as such my debit order has bounced. I have found out one cannot go into an MTN store & pay them cash as they won't accept it 😡. Then to make matters worse once you have paid into their account you cannot speak to a customer care agent to get your service restored, because their signal is so bad they keep breaking up so you cannot hear them & they cannot hear you. This after you have called 135 thirty times trying to figure out how to speak to an agent as this option is hidden under the other 29 options. We pay for a service why do we have to jump through hoops to speak to a person???? I have used MTN for 20 years, but if this is what they call customer service they can say goodbye to me as a customer. As it is I have already canceled 3 contracts, if there service doesn't materialise soon I will be canceling the current contract & going elsewhere.
