poor service and no communication

Its now day 8. No feedback received no customer service. Iv spoken to numerous service "champions" and all agree that i have not missed a payment. I have had my line suspended 3 times now. I use my line for business and can not operate. Everytime I have called in i would have to wait over 10 minutes as they system is not working. Is this how MTN treat customers that have been a loyal customer for over 10 years? Am I still expected to pay a full monthly premium when my line was suspended for weeks on end? What sort of compensation if any would you suggest?
