Claiming to be eBay customer support services

Like others here, I got an "invoice" attached as a jpg to an email which thanked me for my order (except I hadn't placed any order). The invoice is headed Zip!Pay, the date format is American, the items are 5 Myer e-Gift Cards at $100 each and the tax rate is 5%. Scambo, I reckon. It has come fairly soon after my details appeared on the dark web as a consequence of the Medibank Private pirating.

5 X Myer gift cards. Tried phoning but no answer.

I got a call from them, I didn't understand what they were saying and then he hung up, then 2 days later I got an email with an invoice attached for 6 ebay gift cards at $100 each plus $30 tax going to be charged to my credit card. I am going to try and forward email to ebay security

Number on fake invoice, pest or scam.
