Your opinion on the source of this spot

I recently sold my 55-210 on Ebay in good condition with no obvious marks on the lens or dust inside.  The buyer is demanding a refund based upon this image which shows a small dark spot, which the buyer claims is an internal fault in the lens.

I think it is either a dust spot on the sensor, or possibly an out of focus speck on the glass of the window that this image is shot through.  Opinions?

Unfortunately, ebay and paypal tend to side with the buyer in these sorts of disputes.  A little ammo in terms of "expert" opinions on my side would not go amiss.  Or maybe I am wrong and it is an internal issue with the lens.

Thoughts?....Thanks
