I would not recommend complaining for a small refund if it was described well, not to mention it could have easily been missed so not really a lie about the shipping.
This minor damage could easily fit in many descriptions unless the seller would say it was minty without any damage or if the buyer asked for the condition very specificly.
It's Kinda the worst buyer, gives a bad rep and he might pass it of to others since your a hard unreasonable buyer to deal with if you decide to do so wich does happen from time to time.
only if you really asked for the minor things beforehand or if the seller said so specifcly and or listed as mint without the most minor kinds of damage else I would not recommend asking for a partial refund.
