MTN wifi service up to nuggets!!

Intermittant LTE signal for the past 8 days. Trying to report at numerous numbers found on google search, email sent, no success whatsoever. If we get wifi signal it amounts to about 5 minutes per 24hours. This is unacceptable, as we have to buy data to use from either vodacom or telkom. How can a service provider not see that they have problems in certain areas, I bet you, that there will be NO discount when it comes to paying your bill
