How do i get these flamers to stop thinking I hack?

Alright so I make a match in monaco TD 1-2 minutes before the match ends I killed a guy named X-papy-X (I got 55 kills and 15-17 deaths in that match), so he thought that I was walling (I was sniping with my AWM) and now he says that I'm a waller and he's gonna report me - My IGN is Pulchritudin, Clan is NoE. PLEASE HELP ! IM DESPERATE!!!
