Sell direct are *****. Why does Telkom use them?

My wife recently received a call from Sell Direct to upgrade the Telkom lines 3 to be exact. Samsung galaxy tab was offered and the first thing my wife ask was if these were voice lines, if we will be able to make and receive calls and most importantly top up. Mumienah Orrie pushing the sale promise yes thats exactly what the contract is. Mumienah Orrie could not get hold of my wife the next day and called me. I again asked if the contracts are voice and again the **** said yes. Upon receipt of only TWO of the devices we are informed that they are on a data plan with no voice. Can you imagine our frustration after confirming it more than once. I now get told by another *********** Sell Direct employee Aphiwe, that the 3rd device will take two weeks to be delivered. As I told Aphiwe, either the packages get migrated to voice, as ask for or Telkom can come pick up the two devices and cancel the contracts.
