Chess.com message saying I reported someone... I didn't?

I got a message saying thanks for the report about fair play, and they're looking into it. 

I have no idea what this is about. Is there a way to see what I've reported and cancel it? Can you report things easily, like a misclick?

Did someone report me and they just made a mistake instead of investigating me they thanked me? 

 Not sure you read what I wrote. 

Chess.com said thanks for reporting the bad behaviour. 

I haven't sent a report. I'm not aware of any bad behaviour. 

What is chess.com and you for that matter, on about? 

It's possible it was an older report and when the member got muted/closed/warned, it sent that message out to anyone with outstanding reports. It's kind of hard to accidentally report someone, taking multiple clicks, so that's not likely. Also, once reported, you can't un-report.

I accidentally reported someone for abuse, what happens to their account then

Nothing will happen if there's no abuse.
