MTN 173 is pathetic

Hello peter I have such a bad experience with MTN they need to improve their service or if they cant assist clients they should rather close down so we can go to other networks that are able to offer a better service

I have a problem with my network and the matter has been going on for a month now, I am not able to receive calls my phone goes straight to voicemail when people call me and my calls are not forwarded/diverted. I am able to make calls and receive sms's. I think I have spoken to 100 mtn "service champions" whatever it is they that they call themselves, no one resolved the matter they gave ## numbers to cancel diverts and that doesn't work. Then this morning I spoke to a Manager called Themba Lukhele he tried to resolve the matter but also failed and sent an sms to say I must call 173 and ask for him when I spoke to an agent there called there called Thembeka Zwane she asked me to explain the matter again for the 100th time because she couldn't get hold of Themba. This is so irritating am considering changing networks MTN is just wasting my time am not even sure if they log in our queries
