Scam !! Don’t call back

Caller: I don’t know

Went straight to an automatic message saying they were eBay about a cancelled order and refund. The amount they were saying was not familiar so I hung up

An automated voice said there has been an ebay order of $1500 placed from my account and I can cancel the order if it is not me by pressing 1.I did not comply suspecting fruad.

Tried to scam money saying if I didn't call back they had to deduct 9.99 from my account

I answered said it was ebay trying to get money from me

I called back the number (07) 3103 2773 but was routed automatically to an ivr
