Already the fact that I couldn't even make a return. Legally, they don't have the right to refuse me a return (in my country, the seller has to accept any return within 14 days and doesn't really have the right to refuse, it's a right of retraction). Moreover, I can also say that their agent disrespected me and they refuse to give me a copy of this chat (maybe a pressure from PayPal will make them give this copy). Then I have to invent a valid reason just in case to avoid them asking me to return the pair. Do you have an idea?

They're all In support of your claim, so they can certainly be used as evidence of noncompliance from the company.
