Why do you even care what this person says? You
know you have your own cel, who gives a frig that
they think?You aren't selling you cel and even if
you do, it is no concern of theirs since the
sequence numbers are different. Bottomline... 
save your breath don't bother hoping for a
response, certainly not an apology. I am certain
you rather be doing something else instead of
trying to disprove some unknown persons claim,
right? Let it GO.
