Sorry but this is silly mistake done by you not saving what you should, and you can't blame them for that  
You also didn't show a single proof for your claims and I didn't see any other recent bad reports about that service.


I didn't sent proof to a forum of random people because I don't want everyone having access to my wallet. Crazy me, I know.

I did send all the proof needed except the letter of guarantee to them. The reason I didn't save the letter is because I've transacted 2-3x per week for over a year without issue. Not sure why they decided to randomly not send these coins aside from the fact they randomly scam and hope people don't have the letter saved.

If the mixer automatically mixes and sends the coins then there should have been ZERO issue. If it's a manually process, well then that's called selective scamming hoping the sender didn't save the letter of guarantee which I admit was my mistake trusting ANYONE in this space.

Regardless I hope whoever they are suck a dirt di**.

I am truly sorry for your loss. I hope that the amount I mixed was not too large. It is always better not to risk large amounts. If the site is new to you, it is better to try with a small amount to avoid problems so that the loss is less.

You should also have downloaded the letter of guarantee because it is what guarantees your right to recover your money when problems occur, but you should not despair and consider that you have lost your money forever. You should continue trying to contact support, perhaps you will get an acceptable solution.
