Mtn signal loss to SOS all the time

What the hell is going on with mtn these days? The whole of Despatch is complaining about the signal that is so bad, you cant even use your phone because its on SOS mode most of the time. I cant even phone 808. I did phone mtn a while ago and they told me that nothing was wrong but my phone has been off 2 days at that time. They said its my phone. How can it be my phone if everybody's complaining that their usage is on SOS. Whats gonna happen if i have an emergency and i cant even use my phone to get help? But i must pay my contract every month and cannot use my phone.<br> Please man mtn...sort out this signal stuff or i will cancel my contract and take it elsewhere
