I've noticed lately traders are impatient, expecting payment asap likely only a couple of hours after winning the auction. Does trademe allow up to 7 days? Its so frustrating because they place unnecessary negative feedback and I've got over 130 positive feedback

I sold an item on trademe in early June, this morning i got an email from someone saying they haven't got the item yet. I said i didnt sell you anything recently and sent a screenshot from nz post tracking saying delivered 7th of June. The person replied implying they bought something from me last week. I sold one last week to someone in Dunedin and he emailed me to confirm the parcel arrived. Do i ignore this person claiming i haven't sent them this item? I don't understand this

I'm looking for an Air rifle but under the air guns category it's showing parts, under refine option too. Admin can you remove these because there's so many and camo jackets aren't air guns neither is bb pellets
