Query: Worst Customer Service I've encountered in a long time AND faulty product.

I had one of these before and loved it so we bought another. This one was mounted on the wall for the required time and when I loaded it up with products it crashed to the floor and busted EVERYTHING. Upon further inspection, I noticed that the silicone never hardened and felt it was faulty so I contacted the company. 2 months later I am still jumping thru hoops with these clowns. Twice they have said they sent out a replacement product and after waiting over a month both times to receive it they sent the wrong item!! This so easy to remedy: Replace it and I will get on Amazon and rave how great they are. Ask for countless pictures of the broken product, ship the wrong item twice and only answer every other email and watch me go crazy. It's things like this that make you lose faith that there are any companies left with worthy customer service. Don't give your money to these people. They truly do not deserve it.
