MTN the network with no customer service

From October 2020 we have a problem with limited or no signal in our area (Lyttleton manor ext 1 Centrurion) I reported this to MTN coverage support desk with following ref numbers:[#***], [#***], [#***], [#***], [#***], [#***], [#***], [#***], [#***], [#***]. On each report they only reply with the ref no and that they will come back to me in either 10 working days or 2 working days. It is now almost 5 months and the problem is still not solved or any other solution offered. We are three people in our household and all of us have the same problem so it is not a handset problem. So we currently only have expensive paper weights i.e phones. When we try to do online banking we have to drive +/- 5km to conduct our banking as we need signal to receive the OTP from the bank. I forwarded the emails with reference numbers to the CEO as well and it was not even read. I find this totally unexpectable.
