Help!

I’ve had a few people recently having relatives sending deposit checks. I just found one and I don’t recognize the name (I’m terribly sorry).  I’m pretty sure I need to shred this check because a new one for the final amount was written instead, but I’m not sure. Help me out if Lolita from CA sent a $300 deposit for your puppy, and send me an email so we can square this away. So sorry for the inconvenience!!  Thanks!
