A wrong undocumented FEE was taken

[DzmitrySvirydzenka]

By some reason one of request was charged with 0.3% Fee instead of 0.165% in accordance to my VIP4 level. Could you please explain why it happened so?? According to marketInfo BBANK_ETH should be at most 0.2% but not 0.3! Here is log of server response:

I'm really confused.
