Unporting from telkom

I am furious at the service Ive been recieving with telkom. Firstly the call centre agents is unfriendly, secondlly they do not go the extra mile to ensure the problem is sorted out, thirdly they do not know their products and services as I get tranfsferred from pillar to post! not to mention I hold on the line for hours. I recently switched to Telkom from MTN as i took a contract out. Its been almost 6 months now.I wanted to switch back Mtn (unport) as I feel data is too expensive, Im out of network coverage most of the time. Lebogang said she logged a query to the porting department (26 june 2015) and said it would take 48 hours max. What do you know Im still on the telkom netwok and she has not come back to me with feedback. Very annoying actually!
