SUSPENDED SERVICE AND NO ANSWER!!

I am highly irritated by the level of incompetence on mtn side. Firstly for suspending my service which is up to date on payments and for not even notifying me as contract customer via sms of this. This negligence by who ever made this error on my account is outrageous and I will not stand for this level of service from what is supposed to be a reputable service provider. Secondly when trying to make a call the voice activation say to contact the service provider, I have phoned 808 15 times. 8 of those times the call was disconnected before it even got through to speak to an agent and the 7 other times I sat on the phone for 6 to 10 minutes at a time with no answer. I can not fix the issue, I can not make calls and if the situation had to occur where I am in an emergency what am I supposed to because of mtn lack of urgency or helpfulness. How does mtn expect run a successful company when they continue to have issues of providing service timeously and adequately to customers. I have been with Mtn for long time but this is just unacceptable and I am at the point of cancelling my contract. Please fix this issue right away or I intend to take this issue further.
