MTN - Pay for NO SIGNAL (almost three months)

I have been experiencing intermittent MTN signal problems from 14 September 2019 in Moreleta Park, Pretoria East. I work from home, and as such this situation is highly inconvenient. I have contacted MTN via *** (#869273, #869384, #***) and supp**** them will all the relevant information required from me. The last correspondence received from MTN on 12 November 2019 indicates that the site where I get my signal from is still experiencing problems (reference no: ***). As at today, 2 December 2019, I am still experiencing an intermittent signal problem for most of every day. I do not have signal 95% of the time. MTN has displayed very poor service to me, as they have not resolved my concern even after two and a half months of bringing my concern to their attention. This concern is causing me an inconvenience on a daily basis. MTN is also billing me for a service that they are not providing me with, even though they acknowledge that the site that provides the signal to me is experiencing problems.. To me , MTN is an ********* company for charging me for a service that they do not provide me with. Society normally refers to such behaviour as theft.
