Wheel rim bent

Hello, I bought used aluminium wheels on eBay 4. According to the auction description, the rims have “normal signs of wear as can be seen on the pictures”. The tyres are as good as new, because they only drove 1000 km. Yesterday the rims arrived and now I have discovered on 2 rims bent edges. For me these are no normal traces of wear, but 2 flaws, which he did not point out in the description. I am already in contact with the seller, since I This does not want to be left standing, even if he claims that this could be seen in a picture (at least not for me!). Can you continue with these rims without any safety-related risks? What would a repair cost and is it still possible at all?
