service sucks

I opened a contract will telkom mobile on the 08/09/2015 telephonically. The next day a debit order went off my account for the subscription and i was told my cellphone will be delivered to me within 5 - 7 working days. Today is the 5th day and i was told that they will only courier it later in the week and i will receive the phone only in next week. This was not communicated to me when i agreed to the contract and the staff working at the call centre has no knowledge of the products. I argued with an agent about the payments via debit order as she could not explain to me what the debit order was for that has already gone off. Whenever i call in...i always wait for 20 - 30 mins before someone answers. <br> Can they really treat people this way and just say I apologise.....this is unacceptable
