Why wouldn't you say what company you bought the tanks from? If they screwed up that bad, it could potentially save others from the same problems. A company that can't get L x W x H figured out is definitely not a place people would want to order from .
As for that 4ft high tank, you really can't do anything practical with it. Take it somewhere and have them cut the height in half and then you can do something with it.
