Query: Cage not working properly

The cage was a bit difficult to assemble but not too time consuming. However, after assembly we found the cage does not stay open for more than a few seconds. It keeps closing at the very slightest touch. It would not work for trapping an animal because the animal might have the door close down upon them before they were fully in the cage. We have contacted the seller and they told me to contact the manufacturer. I have tried to do so many times, but repeatedly get a "busy" signal with that phone number. The cage is still sitting here and I do not trust to use it on an animal. Something is wrong with this cage.
