Bad Service From Vodacom

I app**** for a contract with Vodacom which was approved on the 5th of March, i was told delivery would take place in the coming days. I was satisfied, on tuesday the 10th of March a package was delivered, the box was empty and did not contain the contract sim card that was supposed to be delivered. I contacted Vodacom through Phone Calls, Emails as well as through their Online Chat Service but i have not made any progress. On the same day that i called their After Sales Department i waited on the line for an hour. Today in the 11th of March i called as soon as they opened and i am still on hold as i type this message. Poor service, i tried to call another number to cancel my contract but i have been waiting on the phone as well.
