CANT RECEIVE CALLS, can make outgoing, shows different number.

I am long standing MTN contract subscriber which leaves me appalled at the poor service support received by MTN (808\135). I have been battling for several days trying to log a basic call and nothing gets done. Spoke to at least 7 agents which puts me on hold for over 15minutes eventually im forced to hang up. After much attempts, one agent took 2 minutes to log a ref call ( ********** 47) to network team but then no feedback.

My issue is that I am UNABLE to receive any calls, however able to make calls but another number is showing when making calls. i.e. ********** 101 and this is not my contract number. Can this please be fixed. Issue is over a week now.
