SUDDEN DEAD ZONE

I recently opened a contract with MTN no less than a month ago, my girlfriend is also on MTN so I thought with her GOOD coverage at home why not join her. We have not had any network communication for 4 days now unless we leave our home. <br> <br> It is like we simply lose all communication when we are at home. Full signal - ZERO data transfer. I cannot even test our signal with a speed test without it giving the error: Network Communication Issues. All of a sudden we have had this issue - signal was perfect before.<br> <br> Called MTN 3 times in past 4 days with each call entailing settings reset \internet"and \""myinternet\"" which does not work and the same response that the towers are fine and no problems reported their side. We have full 3G and LTE coverage according to MTN's coverage map - PLEASE FIX THIS!?"""
