mondo mobile service is ****

We were contacted by mondo mobile in January 2016. Ant they were selling us the wifi router for R 119-00. We ordered 1 and asked for it to be delivered . when the courier company brought it home. They didn't release due to insufficient documents. So we called to have it cancelled. But they insisted on sending it again with certain rules. But again the same encounter with the courier company. Sent it back and told them to cancel. Completely. Know after two months we visited our local vodacom store to purchase one. And our luck it wasn't cancelled. For the past two weeks we calling mondo mobile to have it cancelled but to avail. And know we heard they sent in the application to be approved when we don't even have possession of the device. We are know being pushed from pillar to post. Vodacom says they can't help till mondo mobile don't reverse the approval application. What do we do...
