Paying for no network connection.

For about 10 days now, there is no network connection for my cell phone or the modem for the computer. On my cell phone there is a notification that says 'emergency calls only'. The light indicator on the modem does not even turn to green. I have called the network a few times - a complaint was lodged and they called me back ONCE (I was unable to answer the phone at that time). They never called again. Obviously it is ridiculous that I cannot use my phone to make calls! I have to use data roaming for whatsapp. Due to not having access to the internet for such a long time, I have lost thousands of rands in business, as I use my computer and the internet for my business. I cannot receive emails or answer them. People cannot get hold of me. I am paying for a service I cannot use.
