MTN no Service

On the Weekend I purchased two new lines from MTN, which were activated but were suspended soon after because my Credit Limit was never increased to account for the new lines. Yesterday I managed to get the suspension removed from the one line and but not the other and now I am unsuccessfully trying to get the suspension removed from my last new line so I have a phone that I cannot use and everyone I speak to says it is active and the suspension has been lifted but we cannot help you any further because our systems are offline. MTN we pay good money for a service we are currently not getting please up your game. Time is a wasting on my 30 day cap of data and airtime which you are now currently wasting for me.
