can a modder help me on cod 4?

i bought the game on 11/23/2011, the first match i joined it was modded XP, i got 3,000 xp like, every 5 seconds. I prestiged 6 times that Night, lol, i dont really agree with modders but i thought that " oh well " but around my birthday, ( a month later ) i got into a Free for All match where for every kill you got, it was - 2,000,000 XP, after getting 2 kills the modder kicked me out of the game and i was level one 6th prestige. so then i was playing and not leveling up. :( Around valentines day, some guy did a "message to all recent players" message, and he said he could get anyone up to 10th for free, and i wanted to get to tenth all legit, so i thought i just needed to be reset so that way everything was DEFAULT. so i asked to be reset and we did the mod, but now im level 1 prestige 1 with - 2,000,000 XP until level 2, and i cant play any real online games, which really sucks because i LOVED the quick scoping in that game. I was just wondering if anyone could mod that XP for me PLEASE PLEASE PLEASE? p.s. i got no mic :/
