MTN Call Centres dont answer

I have a problem my bis and data seems to have been disconnected. I have phoned 808 and after following the voice prompts I get told to contact 1555 then I do that and after following the voice prompts I get told to phone 808... I mean really!!! Then I email them via their website and no one replies... so then I try phoning and holding on for an operator and 20 minutes later I hang up. I have phoned a total of 4 times since yesterday and every time there is a message that they are experiencing high call volumes.... then guess what? Improve your service or increase your staff at the call centre. No one has the time to sit and hang on while you people string us a long like puppets. I want my problem sorted out now! this is a business phone and I have no emails.
