Lack off service and pathetic calls centre

I was querying an order - delivery of DSTV explora with a special i had purchased - held on the line for over half an hour, was given the number of a courier service who would supposedly give me the status of my delivery, but they referred me back to telkom. Tried calling telkom again - twice - only to be told that they were having problems with their line and could not hear me. I tried again later, got through (eventually), explained my issue, to be met with dead silence. Could they hear me? Did they hang up? <br> I have also emailed telkom who have since not responded. <br> I would like telkom to contact me asap and deal with this frustrating issue
