Thank you for your reply, appreciated
The note is there as I called to ammend the stamp, the officer told me he will leave a note saying that the stamp date was wrong and was 3 days earlier than it should be so my concern is that maybe he wrote.slmetning else too

I'd say you are too much overthinking. Just relax!
 
It's really annoying that they do this sort of thing -- I had a similar encounter whereby the date of vehicle import, June xth, was stamped as May xth -- a difference of an entire month!
