MTN customer service

I have been getting bad customer service from MTN from emailing and calling them for assistance. For the past 2 weeks I have been asking them to come take their router since I can't afford to be using a home internet that is not uncapped that only last for less than a week yet I will have to pay R400. They **** when they said that R400 package is uncapped. It doesn't make sense for me to have home internet that will last a week and have to spend more money to have data that will carry me throughout the rest of the month. I am tired of calling and emailing the going back and forth with them. Another funny thing is that even though their router is in a box and I am not using their home internet it shows in their app that the data is depleting how is that even possible. I am frustrated and angry.
