Query: WHAT A SHAME!

I bought this air bed after much considerations and ofcourse my budget.Yes i received it on time.But this item started to deflate itself the first night. the first night i assumed that maybe, i didnt fill it properly. second night , the same thing. Actually afer my return from my July 4th vacation (i was away for three days),you can imagine my shock to find it deflated all the way to the ground!I was not impressed
