Ebay is telling seller to refund buyer by a certain date. Of course
there is no buyer, but ebay is only as good as its programming. Will
seller get a defect for not refunding?
You need to call ebay and see if they can fix it. I wouldn't think it
would result in an unrefunded defect since there is no buyer, but I
would not trust to leave it unresolved.
You have purchased this product from 2 different sellers and seem to be
having the same problem of losing eggs. Could it be that you are
misusing it or it is not meant for that type of fish.
