Lost screws

Not good The top door did not slide good because I found a lost screw in one of the tracks I was able to fish it out. The bottom door was a total disaster it would only open half way and I found one screw and two nuts in the bottom. And guess what, another lost screw in the track, I had to dismantle the whole thing taking the track out to fix. (1 1/2 hrs) later. Then when I got everything back together some plastic piece and spring came off the top on the inside now it doesn’t soft close. Would you guys like to send me another unit!!!!???
