I think that the OP had a legitimate problem in his experience with Whiteflash, assuming he told the truth. WF should have made it clear in the first place that the original diamond he inquired about is officially not available to be sold by WF because the company''s insistence on quality. They way he found out the diamond''s unavailability is significantly problematic, I feel. (Even though I personally had a positive experience with them buying one of their in-house ACA diamonds.) It could be a communication problem indeed, where the sales rep meant that a diamond roughly meeting the customer''s requirements has been found and is available. Yet the OP has a good reason to be suspicious of WF''s business practices standard, given that he almost bought a different diamond than he thought he was buying. It made things worse that the diamond the sales rep recommended costs more than the original one he requested.
On the other hand, I think the OP perhaps should try to understand that the "call for availability" diamonds are not really being "advertised" in the traditional sense. They are listed as such because they are not in the vendor''s inventory and probably have never been seen by the vendor. The business model of the online vendors here relies on the fact that they only sell what they have seen to ensure quality. It should be perfectly acceptable if the vendor comes back and tell the customer that the inquired diamond is not available for sale because of quality concerns or available only with conditions attached for the same reason. Most customers wouldn''t mind listening to suggestions for alternatives at that point, but I don''t think it''s fair to think of it as a form of baiting.
