Just wanted to share a scam experience I had in Melbourne for others.
Someone contacted me to buy high value item I was selling. When they came, the person advised they are the buyers "brother" rather than the buyer and the buyer will make the bank transfer. Already dodgy but I provided the BSB and account anyway, then the buyers brother had printscreen showing transfer complete. I requested ID and buyers brother advised he doesn't drive and took Uber, but he sent me buyers ID. Buyer was with same bank so payment should have been visible straight away (and I think even if different banks, can see straight away these days). Buyer over the phone was trying to convince me that the payment takes 24 hours to clear and was demanding the item as they were heading out of town following day. I advised cannot take item until payment received and that they have my address, so they are welcome to come back following day or I can transfer the money back when received. The following day no funds received, as expected, as it was a scam. I checked their gumtree profile and they had some negative feedback compared to previous day, so seemed they spent the day trying to do the same scam to others.
Sharing my experience as warning to others and reminder to make some clear rules upfront before buyer arrives to avoid scammers. I understand Gumtree is risky and even dangerous, so I was lucky, but seems crazy to think they have possibly a fake ID, two burner phones (as I have both the mobile numbers they used) and he do not have problem being recorded on my security cameras (or didn't notice them). Had they been successful, it is pretty much no different to stealing, except they can try to play dumb regarding transfer. While on scam topic I have had a situation in the past where someone tried to get an 'Air Tasker' to pick up an item and they gave 'Air Tasker' neighboring address, which I stopped from happening. Times are tough with covid so these scams may increase.
Cash or nothing.
