Never use telkom, worst network ever

I'm reporting this complaint on behalf of my BROTHER. He has a telkom lte contract with telkom. It was working 100% fine until a few weeks ago. When ever he is at work the useless network doesn't work but when he is in town or at home then it's working fine. He called the call center and was busy with someone who was trying to assist him, he airtime got finished and the person he was busy with didn't bother to call back to sort it it. I called 10210 on Monday this week and the guy gave me the number 081183 and asked me to call that number, that number just give me an engaged tone all the time regardless of the time with still no luck. I logged a complaint on Tuesday via telkom website and got the message stating that an agent will call withing 24 to 48 hours, that time frame has passed and now my brother is absolutely ****ed off as he needs the internet for work purporses and he has to come home and connect to the internet to do his work which is unacceptable. He is now considering changing his mobile contracts and his adsl to another network because it seems telkom is just useless, quick to take your money but when you need the service you must run and beg for it. Unacceptable
