NO MTN NUMBER WORKS!!!

I have submitted an insurance claim for a cellphone on the 17/09/2015 and to date has not had any feedback except for the mail to confirm that my query has been received and is being attended to. I have sent 3 mails to follow up but also with no response. The contact number *** has been experiencing network problems for the past 2 weeks and you cant get through. Even ***, *** and *** is of no help as I cant get through to speak to somebody. I must say MTN has the worst customer service interface I have ever experienced. You have to hold on for hours and cant get through to speak to someone other than a machine. The same story goes for account queries.
