Useless customer service

Useless customer service. You are ALWAYS left on hold for atleast 15min and when someone eventually answers the phone they are useless. I have no Wi-Fi connection and phoned Telkom twice, sent an sms requesting a call back and reported my problem on the Telkom app. The one time someone answered the phone she was irritated with me and told me to turn the router off and on (as if I haven't tried that) and then we waited in silence for 10min untill I tried asking her to reset on her side (the obvious reason for phoning the service provider). My airtime ran out and there was no phone call back.
