13 days after approval - STILL NO PHONE!

I app**** for a contract from Vodacom on 3/02/16. The contract was approved on the same day. I dealt with a lady named Derasha. After the approval, there was no other feedback. Today (16/02/16) I call in to the call center on ***4. I get through to Zanele. I explain the problem only to be told that the product I ordered is no longer on special (was on special at the time of my application) and Zanele is unable to assist but happy to pass me over to Charlene who explains that she cannot help me either as Derasha is 'locked in' the application. So I ask to speak to a manger and surprise surprise... ALL managers are in a meeting until 4.... How is that possible that no senior staff are available for 4 hours or more of a business day???? I cannot express my disappointment with this situation. As an existing client of Vodacom for many years, this is definitely NOT the kind of service I would expect. Please rectify immediately!!!!
