Urgent, Help please

Halo Waypoint keeps confusing me with someone who had my gamertag previously. My old GT was Herijuana and it is now Biologikal. I’m a Nova on Halo Reach and the kid who had biologikal as a GT before me was a Warrant Officer Grade 1 and his rank shows up on my Halo Waypoint so i cant track my rank and KDR on here its really annoying. How can this be fixed? PLease Help
