Returning VODACOM Goods is a nightmare!!!!

I upgraded my line using the app. However, prior to the package being sent out for delivery I called Vodacom to ensure that everything was in order. Not to my surprise to be honest (due to prior online bad service), the order was incorrect. It wasn't an upgrade but a new line altogether. I alerted VODACOM whose 3 consultants advised that I wait for the parcel to be delivered and send the driver back because their hands were tied. I alerted the delivery to not come and send the item back to Vodacom. It has been over a week now Vodacom is not taking responsibility to expedite the process of the couriers sending back the item. When you take a debt with them they can even deliver overnight. But if you're sending the wrong items back you may have to wait a lifetime!!!
