Bag Signal

I have called the mtn customer service Centre in October complaining about the bad signal I have in my area, they told me the technician knows about it and will sort it out, I called again to follow up and they said the same thing, I left it and just stayed with my bad signal, now it’s December and I STILL have the same if not worse signal , I can’t make calls or receive any calls or do anything that involves data when I am home, I called again yesterday and the guy said he can see I called in October and it says issue has been resolved, and I told him no it has not I just stopped calling coz no one bothered to notify me about anything, he then said a technician will call me , no one has called me and still the signal is bad, I really had enough of this.

All I want is for Mtn to please let me know what is wrong with the signal and when it will be resolved, this has been on going since October.
