Future reference , if this happens again and the items are from Amazon , just call Amazon support. They'd have cleared this up in one call.
I had something similar happen with a GPS unit, the delivery guy delivered to the wrong address , someone else singed for it and never seen it again. I tried to play nice with the seller since he was a small independent, but from the get go his demands were ridiculous . So I called Amazon they refunded me instantly; but this is also why sellers don't like selling through Amazon. I guess that is how corrupted business has become in the states when sellers wont refund or deal with customers , but complain because they feel they are being ripped off?
