MTN is unreliable and ***********

My cell phone services was suspended for no reason at all. My telephone account is fully paid and up to date. The call centre 808 number is a disaster. No matter what time of the day or night you call their message says they are experiencing unusually high call volumes. I am unable to speak to anyone after trying 4 times and waiting online for 20-25 minutes at a time. The call gets cut. No one in MTN shops can assist. <br> I run my own business and need a fully functional phone at all times. I have NEVER defaulted on any payments. I have 78 students writing exams who need to get hold of me tomorrow and I cannot get any MTN assistance. The online facilities is of NO use to try and resolve this matter.
