my vouch thread problem

[futandrs]

So I refused to sell this guy IKOV gp for extremely low price, and he's now claiming I'm a scammer on my vouch thread without any chat proof nor did he submit a report or anything, and this is/will ruin my reputation which i've been legit building for 3 months and gained 10 vouches, but he ruined the vouch thread by saying i scam without proof, what can be done?
