Rude seller

I talked to a seller wanting to sell a damaged ps5. Negotiated a bit and he made me an offer. I told him I would pay him his last price he said he would accept. Then he swore at me telling me im a cheap **** and all kinds of things. Reported the convo and the add to gumtree but they just seem to be ok with it. Clearly money is the only thing gumtree cares about. So sad…
