I absolutely understand; I used to be a repair tech for Sprint. That said, screen repair for the Pixel 6a doesn’t even require the back to be removed, so I think it was more an education issue than anything else. I don’t think it was malicious at all, but shortly after I noticed the NFC issues, the back fell off and I saw they’d cracked it pretty severely and stuck it back on with double-stick tape. It was less the crime and more the cover-up that pissed me off.
Unless they went to a scratch-and-dent or secondhand place, then I can imagine it’d be a lot cheaper
