sorry for your trouble, but ????
Leave them what they deserve, bad communication, poor and not on time shipping, wrong product, delayed responses, all of these are negative.....it is not the first time. My deal did not go thru ebay so I was not able to leave any feedback, do what you need to do.
Good Luck ????
If you follow thru and get your sheetmetal, let us know about the quality and fit etc. also interested to see the box/manufact.
