Telkom is taking too long to sort out a problem

on Wed 22 July i contacted Telkom Mobile to report a problem with my Blkberry- i cant send/receive emails on my phone. i had previously contacted them & the operators failed to help me sort out the problem. on Wed they logged a case for me & said it take 3 working days to get attended to by their Data Dept. Monday being 3rd working day, i contacted them to be told its NOT 3 working days but 72 hrs- i told the lady its the same thing. then she says its 72 working hours- with 8 hrs per day- which means 9 days! why cant they say that clearly when they log a case? my case Ref No:***2. i even contacted Blackberry Help on Twitter- after a few attempts at trying to sort out my problem, they said my service provider must log a case with them for live investigation. I even installed backups of my old phone and when I try to send an email, it says: Transaction error-failure at service. I even sent new service books but nothing works.
