Vodacom poor services

I app**** for a SIM contract and everything was approved. On the same day, I received a message confirming that my parcel had been handed over to the courier.

A week passed without me receiving the parcel. When I contacted the courier company, I was informed that they had been given incorrect delivery details. Each time I called the courier to update my details, I was told that the update could only be done if Vodacom provided the correct information.

I contacted Vodacom repeatedly, but my details were still not updated with the courier company. Eventually, I asked the courier company to return the parcel to Vodacom.

Vodacom then informed me that I must wait for an SMS or notification confirming that they have received the returned parcel so that I can proceed with cancelling the contract. I have since called Vodacom again, and they confirmed that they have received the parcel. However, I still have not received any message or notification to allow me to move forward with the cancellation. It has now been several days.
