NO-KOM (Read - TELKOM)

I have an uncapped LTE contract with TELKOM. Since Sunday morning no signal. They had me chance settings etc. On Tuesday I brought the modem to my work, to find it working fine. That mean that there is an area problem and not the router. Telkom still insist that the settings are incorrect. They should be in the NOT COMMUNICATING business. And I am paying every month.....
