Speaker purchase question


I have been a member here for 22 years, but encountered something today for the first time and would appreciate your opinions. 
I bought a pair of used speakers on Agon and they arrived with no grilles. The seller is stating that the pics did not have grilles (true) and they were not mentioned in the ad. These Rega speakers did come standard with grilles originally. I thought that the pics were taken to show the condition of the drivers. When I asked the seller, he said that he had looked into buying new grilles, but since he didn't mention them in the ad, it should have been obvious they weren't included. 
Am I wrong to feel deceived? I want to be reasonable and would be interested to hear other opinions.

The sellers "fault" is his lack of awareness anyone purchasing his speakers may assume grills are expected.

His reasoning  "what you see is what you get" unfortunately is correct.

I would have asked before hitting the buy now button. Buyers responsibility to ask everything before purchasing and make no assumptions.

Time to go to Home Depot as mijostyn suggests, if you must have grills.
Strikes me as someone doing something while driving that is discourteous but not illegal. My course of action would be determined on his reaction. If it showed a genuine lack of thought and remorse for not telling you, I would let him off the hook. If he was being legalistic, I would give him grief and a bad review. It should have been mentioned in the description. Minus one star no matter what.
Also, like someone said... upgraded tweeters... that is a cause for alarm.

Bad reviews cut both ways; the seller also has the right give the buyer a bad review for failing to ask questions and--admittedly--buying on (false) assumption.





Should had sold with the grill that originally comes with the Speaker from the Manufactured unless the Seller stated on the ads, period!. 
When I sell anything I am very specific about what is being offered. If I was listing those speakers I would have specifically said they come without the grills. In your situation, I think you’re out of luck and I would contact a Rega dealer to see if you can get the grills, since they are important to you
