Vivexotic Repti-Home Maxi Vivarium (Medium) Black

The packaging was all bashed and open so was worried that maybe some of the items had come out it was broken but luckily there were no issues. Only issue I’ve had is the fact I have 2 bottom runners and it means the glass doors won’t stay in. I have contacted internet reptile about this when I built the vivarium over a week ago and since not had a reply
