Is @booster scaming it's customers?

I sent 3 SBD to you, to participate in a biding round.

Your ROI was positive till the last second (you can look this up at https://steembottracker.com/ ). The minimum amount of upvote should have not been less than at least 6$. You upvoted with only 2.40$ which is less than half.

Please refund my 3SBD bid or fill up your upvote on my post to at least 6$

If you will take no action, I will spread the word about your foolish behaviour and your scam upvote service, besides flagging your posts.

I noticed, that I am not the only one having trouble with your service, better take some action right now before people getting really mad.
