I received 2 Quantum industrial units on 3/7/17 and the vertical posts had holes that did not line up with shelves to use bolts as per included instructions and clips too loose to secure shelves. I called and spoke to John at Customer Service and told him I received 8 incorrect posts or 14 incorrect shelves and the order was botched. A week passed and no word back. I called Quantum mfg. On 3/14/17 and explained the problem and was told by the SALES Person she couldn't help me because I was a Northern Tool customer and I all issues had to go through the NT. I explained I did call a week earlier but had not heard back. Unbelievable. I found an e-mail from NT on 3/18/17 with a link to send pictures to a contact at Quantum. I sent in pics and still don't have a satisfactory resolution. WTF. Buyer beware!
