Game tag is (removed by moderator - no naming & shaming here), I hope I get some retribution for this crap!
No you won't get your stats back.
You get enough warnings
They can't fix the stupidity of people
Read all of the other posts in this thread instead of just posting "fix this".
If you prestiged your player, you did not do so by accident. It takes a lot of click throughs asking, "are you sure", and even explains your character will be reset to level one, and you'll have to re-unlock the weapons as you level up. There is nothing Treyarch needs to do. M
The same is true for prestiging weapons; you are told, prior to prestiging the weapon, that all attachments will have to be once again unlocked. I'm sorry if you clicked theough all of the explanations as to what was about to happen, but you did it to yourself, and have nobody to blame but yourself.
