Bad service

Telkom service is very very bad! I took out a WiFi contract which I am paying R899 per month for an capt WiFi. I HARDLY HAVE SIGNAL AND CAN'T USE MY WIFI. Since 29September 2019 I made more then 20 calls trying to get someone to fix this problem. Till today no one could solve my problem. I asked today to speak to a team leader and he/she does not want to speak to me. PLEASE PLEASE STAY AWAY FROM TELKOM! THEIR SERVICE IS VERY POOR
