Secret shopper scam

This is a screenshot of priority mail sent to me by timecodeoutsourcing.com <https://paste.pics/58a518033ef58f6641f6de9cf8814819>. I didn’t include fake cashiers check but a legit organization wouldn’t ask for gift card codes. how can I retaliate?

@erickoenig#74993 Lemme give 'em a call.

Their phone number is: (917) 924-2118

Phone number is offline, rings then voicemail. Sounds like TextNow.

Called him and spoke to about 10 min, I could hear his ICQ e-ohh’ing in the background.

He asked me to tell the info of the store cards, pin etc, I asked a few times for his ICQ (so I could send him storecard_info.txt.exe) but he wouldnt give it. Even told him I was getting errors trying to text him, he didnt fall for any social manipulation.
Bad comms ended the call

Sounded like an African accent
