My wife bought this for me for Christmas and haven't been able to use it yet.After putting it together I find out the screens are way too small.I called customer service and they sent me new screens,but the same size as the ones that came with it.Called customer service back and they hung up on us when they didn't understand our problem.Called back and the woman said to turn the base (the part that sits on the ground) upside down.Totally the wrong information and how will that change the size of the screen opening?The instructions are useless and their help very unhelpful.Can anyone help,or do I just take it back and not buy anymore of their products?
