I want my Device or Money Back. 30 days too long.

This is my second complaint now. I'm getting so frustrated. I logged a complaint last week and i was told on reference number SM165729 that i would be contacted with regards to my device which i have now been waiting for almost a month for. I still can't get hold of the sales department and i have logged almost 50 call back requests just last week alone. I want someone to contact me today and refund my money. I'm going back to Vodacom even if I'm paying more. This is not right. I WANT A RESPONSE TODAY!!!
