Vodacom upgrade contract Cancellation isssue

I have given Vodacom a 1 star due to the way are handling a incident not of any fault of mine but it is fault between RAM couriers and Vodacom.

I have cancelled a new upgrade contract with Vodacom which comes a p30 lite. The RAM couriers came and picked up the device on the 1 August and now it is approaching a month and they cannot seem to find were the device has gone to so my contract would not be cancelled until they received it in the meanwhile the customer has to wait for their incompentency. I have sent them proof of the collection invoice but the customer has to now still have to wait for their investigation to complete.

I have been a customer with Vodacom for 15 years and have been happy thus far. All I ask if they can cancel this contract and settle their dispute with RAM couriers.
