Very unhappy with service from MTN

We have had the home uncapped 10mbps package for 4 months now and it has only worked properly for 1 month. We spent hours talking to the help center just to be told that we must stop calling them as there is nothing they can do. "There is a technical issue, and it will be fixed when its fixed" is what I (the customer) must hear from the help center. However, there is no technical issue when the debit my account every month for a service I do not have. So very unhappy with MTN and I will express my displeasure on ALL social media platforms for everyone to see until my issue is resolved.
