How can we pay for something that doesnt work

My husband has a contract with You. <br> His phone was switched of about 2 and a halve weeks ago. I tried to get hold of your so called \call centre"but on the website it only said that its under construction. Then I found out that the call centre is on strike and that unfortunately for the clients that is with MTN nothing can be done. So I tried to phone the Bethlehem branch to find out how we could fix this. The phones just rings. After letting it ring for about 20 minutes somebody answered the phone. The gentleman on the other line was very apologetic and tried to assist me. I then only found out that his account was not paid. I quickly made payment and send proof of payment so that his phone could be switched on. we waited about 2 days and the phone was on. Then 3 days after that the phone went of again. yet again I could not get hold of anybody and so I just paid again. its been 5 days since and still his phone is not on. My husband needs his phone for business. if you cant provide a service then close your doors for good. there is lots of other service providers in SA."""
