Help with seller

[Backforfun]

Hi All

Question I bought a car from a seller who I will not name yet! as artr

I waited ages for it However the seller gave me a small refund for the inconvenience

When it arrived there was no lipo and I was promised this would be posted this was now a couple of months ago

Still nothing and now he is not responding on this site or FB

I can see he is still selling on this site

What should I do for the best ? Is there admin I could go to
