Worst Customer Service I have EVER experianced

I logged a complaint regarding two of my numbers via the call centre in January 2015 and guess what, it's still not resolved! So when I phoned back the first time after the 48 hour turn around time the call centre could not pick up my query logged even though I gave them the reference numbers that they provided me. So I had to log another query again and those queries are still not resolved and I was promised it would be escalated and resolved three times, but till this day nearly 4 months later still nothing. And following up on your own query is no picnic either you spend nearly an hour holding on to speak to a consultant and if you are really lucky, after you have held on for nearly the whole day, they don't drop the call as soon as they answer. I also went onto MTN's website and logged a complain in the section for complains, but would you believe it there was no response on that either and that was on the 20/03/2015....seriously why have a compliant section if your just going to ignore the complaints anyway? I have been loyal and supportive towards this company but I can't even get customer service in return, I'll take my business els where, no problem MTN. Thanks for nothing
