New contract suspended - Poor Service

I've been having such a bad experience with mtn. Day 4 with a suspended line. My mtn line has been suspended since Saturday, with no notification. The line was topped up and then deactivated. I've sent numerous emails to customer care and messages to be assisted on all social media platforms and not one response. The call centre is useless to because your call does not even reach their consultant. This is ridiculous, my contract is not even a month old, never even received an invoice as yet, but it's been deactived.

Can you please sort out my line and give me feedback... Gosh.
