MTN pathetic, poor service on account

MTN once again showed their incompetence. I've had nothing but poor service from them. Last thursday, out of the blue, my service gets suspended for non payment. My due date wasnt until the 11th of the month, but nonetheless, I paid my account the same day and had my service activated again within 2 hours. So thats the end of that then. Wrong! Yesterday morning I again received a sms stating that my service had been suspended due to non payment!! wait, what? The same payment that I made just a couple of days before must have suddenly dissapeared!! how can my service get suspended twice in one month after I already paid, they reactivated my service and then suspend it AGAIN! And no, I am NOT behind on any payments! Yesterday I send them a message on twitter aswell as through their website contact page and the only response I received was another sms this morning saying my service has been suspended due to non payment. I cant even call them as I cant make any outgoing calls, not even to MTN. Pathetic! Now I have been without the use of my phone for another 2 days!!! Unacceptable and pathetic to say the least! I'm so over MTN and their incompetence its not even funny.
