Delays and empty promises

I took out a contract with Vodacom over a week ago, and am still waiting for the card to be activated. I was promised that it would take less than 24 hours. I have been back to the shop multiple times to ask what is going on, and they cannot give me a clear answer. They claim that the bank is giving trouble, however having spoken to the bank in question, they have not received any communication or requests from Vodacom. So much for “SA’s best network”.
