I don't remember it's name. It might have had "monkey" in its name. It's not the one being advertised now (or maybe it still is but it is not appearing to me). I'm sure there aren't hundreds of mixers that advertised here so if you or anyone can list the ones that advertised here, I am certain seeing the name again would ring a bell. This was last year. The amount they took was $7 worth at the time. I remember I was going make a post at the time but was procrastinating because of the effort I had to put in into making a thorough post (because I was really pissed at the time and I wanted to make a really good post) but obviously I never got to it. I emailed them when it happened but they didn't get back to me.
In all of this your claim, you should at least have something that can show that you really did a transaction with them. Advertising a mixer campaign here does not guarantee that it will be completely effective. The fault could be yours or theirs, but without providing sufficient information and proof of the transaction between the two parties, your accusation is worthless. You are accusing a service of stealing by failing to refund your coin. You must ensure that your claim is true before proceeding so that other members can investigate the accusation you've just made about being duped by the mixer.
