Hi,
I have been facing an error of having $-2.89 minus credit on my account. Bought my credits a week or two ago. Can i have some assistance?
There’s a possibility that may Full VPN mode consumed your credit if you have had enabled it then did something like watching a streaming video.
Credit calculation can be delayed around 30 minutes to 2 hours so you may belated notice that
My Full VPN mode is not on. I have been watching youtube and twitch for the past few months and it has never used my balance before. Even checked yesterday before i play dota2. was at $3+. Dont think that afew games of dota will consume $6 dollars of my credit from what i know.
Not sure whether this issue is related with CDN and Mudfish but I’d reset your mudfish credits. 
Please let me know if this issue happens again.
