I just received an Advance shipping notice for an order I made from a website, not ebay, and in that notice the Sender details had this phone number.

The notice also had an address: G2/391 Park Road, Regents Park, NSW 2143

Looking that address up returns a warehouse fulfilment space owned by 4PX Global Express Service and used by multiple businesses including the official AU warhouse of the website I purchased from. 4PX is a company in China used by over 20,000 merchants worldwide. Two independent parcel trackers, ParcelsApp and OrderTracker, were able to look up the tracking number in my notice showing the delivery progress of my order by 4PX.

FWIW, the notice I received was by Team Global Express (teamglobalexp), not 4PX.

Caller: I don’t know

Did you get your parcel? We are awaiting same at the moment. Bought off a website, not email.

This number is being used by an online seller who is a scam

I had a consignment email with this same number as the sellers phone.

Same as you. No answer

I bought off a website, not ebay. Seems a bit suspect also.

I bought items of eBay and they never arrived at my house. The online seller number is (02) 9644 1851, but the number keeps saying "service difficulty" so I can't get to contact the eBay seller and find out if my items were sent. I spent $1200 worth of items and I get nothing for my money. This number could be a front for a sham eBay seller.
