This number appeared on a scam email I received with a fake PayPal invoice for $691. When I called the number the operator stated that I had called PayPal Australia Support Centre. I said "na I don't think so" and they hung up on me.

Caller: Scammer

it was also via email. the address of paypal is correct Level 24/1 York St, Sydney NSW 2000 but the actual number of paypal Australia is 1800 054 378 which means the (02) 8528 1986 is the first red flag since most businesses use either the (02) or 1800 and google maps tells me that the 1800 is the actual number and they have a physical address, so this number (02) 8528 1986 is pretending to be an actual place. Double check the address of the business and their number on google before sending money or doing any further steps. Also I do not have a coinbase account, they said I do which was the second red flag.

I received an email about a Paypal transaction, I tried to calll the number twice with no answer, then looked up the number here and saw it was a scam.

I just received a similar mail, same amount. Didn’t check in any of suggested kinks
