Telkom call centre wasted 74 minutes and still no one knew what was going on

with telkom losing thousands of landline clients and clients to ADSL, one would think they would go out of their way and go the extra mile for clients --- no such luck. we are going through 20Gig of data every 7 days and I need to know why . I phoned 3 different numbers , got pushed from pillar to post and still got no joy- think it's time to look at other service providers! VERY angry and disappointed client.
