seam at center of e-Stone (http://g603.net) sink

we fabbed a 160" top with a um 55" from the left end so we opted to have less visible seam and (http://maplered.com) put the seam through the um and (http://maplered.com) we are really catching a lot of heat from the supplier . just wanted some input what the experts say we are being treated like we have done something wrong.

thanks in advance for any input you guys might have.
