What a poor service

Complain:

i would like to log a complain against my service provider Telkom , i have been in contract with them for the past 4 years and now i have network problem with my router that is always offline every minute does not have a permanent network, it started from 25 February until now it frustrate me because sometimes i work at home and it does not function properly.

i have logged serveral incident to their customer care line but there was no improvements from 25 February until now still waiting for the technicians they did not respond but month end of March i paid the money of the data i didn't use this is so unfair.

kindly assist me to solve this matter as it is becoming a severe issue that is persisting.
