Data SIM not activated 6 days after delivery.

I attempted to take out a new SIM-only data contract by using Vodacom Online. The SIM card was delivered by the couriers on Wednesday, 14 August. After unsuccessfully trying to activate it, I phoned the Vodacom call centre, who blamed the couriers, RAM, for not notifying Vodacom that my SIM had been delivered. I phoned the call centre multiple time. 6 days later, the SIM card is still not activated. Totally useless so-called "service." If Vodacom cannot resolve this by close of business on Tuesday, 20 August, I demand that the contract be cancelled due to non-delivery by Vodacom.
