No coverage or service

We have an unlimited Telkom LTE account. For the last two weeks we had NO coverage, we went instore to report this four times, we have sent emails almost on a daily base, and yet there is no reply, no response, no explanation whatsoever. Even the staff instore were complaining about the blatant ignorance of Telkom towards their lack of service. This is the second time this has happened. It is so utterly disappointing. How can we pay for no service?
