Delivered my shipment which cost me $251 and month later got a charge for $537 for weight issue. product was only $630 that I shipped. I have contacted them several times to get this resolved without any response back. I had the delivery sitting in my garage for over a week and once I opened it there was damage and also a part was missing. I have no unable to file a claim with them for that as it's only 48 hours to file a claim. I emailed them on this without any response. Now I get a charge of $537 additional for this. Scamming the customer without having the customer discuss and agree on anything.
