Bad service MTN

Please explain to me why i suddenly dont have a good network coverage. Or a good signal.

Im still in the same house for 4 years now and since last year June i have bad signal. Ive reported this to *** on 18 November 2020 they said there was a problem with one of the towers, ive reported and phone on several times and everytime they will get back to me but they never do. I only get automated emails but no one is getting back to me about this. I have also send an email to customer service still no reply. Ive also send private facebook messages still no reply. Im so fed up with this situation i want to go and stop my debit order..

Hope to hear from you soon Rozelle Laubscher ***
