Hi there, I bought an item today and the seller only wants paypal as a payment option. They have acted quite strangely and aggressively and even though I only bought the item today, they have already given me negative feedback about not emailing them back after 2 hours (I was at work so couldn't.....). Is this a scam?? I have a bad feeling about it now and I don't want to be ripped off because its a lot of money! Who in trademe should I contact about this?
