First off let me say that i sincerely appreciate Shapeways and wish the company nothing but success. I plan on being a lifelong customer. With that said.. A moderate to large order of parts that i ordered in stainless steel were delivered but they were made of a crusty, ridged "gold like" material instead of stainless steel. After further investigation it looks as though this is the "gold matte" option that Shapeways offers which i didn't order. Ive ordered from shapeways prior to this order and following with no problems but its was the largest and most important order that happened to run out bad I've reported this to Customer Service complete with detailed photos and while customer service admits they are unsure as to why the production error happened on their end i haven't made much headway with regard to a credit so i can reorder the parts or simply having the correct material parts shipped to me. I'm already behind schedule due to the this. Has anyone else had a problem like this before? Again.. i *love* what Shapeways represents and appreciate the service they offer,. I just want to have this resolved and move forward with future orders.
