A VERY FRUSTRATED CLIENT

I'm really disappointed with MTN, I haven't been able to connect to internet and I'm unable to receive calls. The phone goes straight to voice mail when I'm called and it is saying I don't have data were as there is data that I receive monthly on the 1st, beside that I had a lot of data even yesterday. I have tried to contact the customer care line I first spoke to Nonhlanhla who told me to restart my phone, I did and there was still no change, spoke to Musa who said there is nothing she can do from his side and transferred me to a department that she wasn't even sure if it's working or not. I was on hold for 20 minutes and eventually hangup cause even she wasn't sure if they are working. I then called again and I got through to Nola who was very rude and giving incorrect information, when I asked to speak to a Supervisor she placed me on hold for more than 30minutes only for the supervisor to hang up the phone while I'm still talking to her and my issue is still not resolved. I called again and got through to Lumka who still couldn't assist me and referred me to your technicians. I can't stay the whole day without being able to use the services that I pay for at MTN, why am I even paying then. I need someone to contact me ASAP who can tell me what the problem is and how is it going to be fixed.
