poor or no signal

On the 7 dec 2017 i logged a case for poor and unstable internet connection using b315 lte router ( had similair problems in 2017 and cases just lapsed without feedback) to date i have made numerous calls without success . On 26/27 dec no internet service. I have done all test possible using another router and another sim ie mtn mbbs 34 telkom from 0 to 12 mmbs. Massive difference between two networks. Very poor service from telkom who supposed to be no 1 but they are not. Very dissapointed as i have no internet during festive season. How nice when you pay for service and you dont receive it. I will demand credit or cancell my contract if nothing happens by end dec 2017.
