Why do they even get paid if they cant do their work

I got dual call / Dual sim from MTN about a year ago. After I upgraded it stopped working. I have logged a query on Hello Peter twice getting some response that they will fix it but no luck. Heres the other two complaints : https://www.hellopeter.com/mtn/reviews/useless-bunch-of-idiots- ********** and https://www.hellopeter.com/mtn/reviews/mtn-dumb-idiots- ********** they keep saying they logged queries to sort it out but they are *****. Kabelo Mosimanyane promised he will sort it out but also a ****!!! So lets try again.

I have MTN dual call on contract. Its two sim cards that share one number. Primary is in my phone and secondary in my watch. If i dont answer my phone it will ring on my watch. If i dnt answer my watch its suppose to go to voicemail but instead it says the number doesnt exist. No joy in getting it resolved. Have logged another 4 queries in the last week with empty proises
