Pieces didn’t fit and now I can’t unscrew them to take it apart. The 2nd Bark is too large and the top base won’t sit on top of it. This was ordered as a gift so I am just now trying to assemble. I tried to order replacement, but it is past the 30 days. I have tried to take pictures, but your add photo option is not working for me. Please help, I would like to have replacements by Christmas.
