Query: Major disappointment -- cold drinks that spill every time

I purchased this item a week or two ago and have been using it daily since then. I make drip coffee into the container. The coffee stays hot for maybe 1/2 hour and then is too cold to be good. Even worse, I end up with coffee on my desk *every single time* I pour a cup from this thing. I tip it forward to pour, but whenever I tip it back to stop the pour, even if I do so *over the cup* into which I'm pouring, I end up with coffee flowing over the spout and down the front of the item onto my desk and papers. If I hadn't throws away the packaging and receipt, I'd send this back straightaway. "Completely unsatisfied" would be a good way to characterize my feelings about this item.
