Unnecessarily suspended line

I am truly frustrated with MTN..My line was unnecessarily suspended,after I received a message 3days ago and me phoning MTN to rectify and make sure that it's not the case and the lady promising me that it must be a mistake I must just ignore the message as everything on the system looks fine..This morning my lines were suspended,where I tried phoning MTN again, after the 4th successful attempt,I was informed that I should call back later because their systems are down so she can't help.Half an hour later I phoned again.Where the gentleman says he can se that my line should'nt have been suspended but he can't open the lines,I should phone back after 8 o'clock after their finance department opens up.At 8:30 I phoned again,once again the consultant says he can see everything is in order and that my line should'nt have been cut.But unfortunately the Finance department is'nt open today,due to it being Ramadan.. So I have to call back again tomorrow..I work with my phone.So because of somebody else's mistake,I have to go without a phone for an entire day,not being able to connect or get in contact with clients..and hopefully being able to be helpt tomorrow,which will also only propably reflect after 24hours after being opened..I'm truly furious and deeply frustrated about the service at MTN..This is not fair!
