No LTE network since Christmas but Telkom still charges.

I have an uncapped LTE network bundle from Telkom, since Christmas I have no connection, I troubleshot myself testing the SIM card on multiple devices,Results: it's a Telkom problem. I logged a call and received a reference number that a technician would be sent shortly (2 - 7 working days). In the new year I followed up as has heard nothing from Telkom (PS. paying for Pay as you go data in the meanwhile), Telkom advised it hadn't been 7 working days yet. Someone would call. I followed up again 3 days later as 7 working days had passed, they advised they would escalate, followed up today and still nothing. In short, no LTE connection on an uncapped contract since Christmas with zero feedback from Telkom besides empty promises that someone will call.
