Stats adjustments from hacking!

This is my first foray into online gaming, and I don't know how to "catch" hackers.  All I know is that I've played 60+ hours on this game, and it seems like there are some players who are benefiting from something. I'm loathe to call anyone a cheater, but, as I've posted on another thread, I consistently come up against players who seem to have mystical abilities.  For example, I snuck up on one player, unloaded 3 shots to the back and he/she suffered no damage, turned around (while I continued to fire) and shot me once with a weaker blaster and I was dead.  When the death screen showed, player had zero damage and no power up star cards that would have rendered his blasters stronger than mine. If this happened once, I would chalk it up to accident or me sucking, but it happens ALL THE TIME, IN EVERY GAME.  Also, there are some players who seem to have magnets or trackers attached to me or something; same player shows up within 5 seconds of me spawning, not matter where I spawn and kills me 8 times in a row.  Seems fishy.  All I know is that I've muddled my way up to level 28, 2000 points at a time, and I still seem to consistently die from one blaster shot  while my opponents live after 10.
