GRIN Behind working agents

I have paid a lot the money buying YouTube and reviewing videos. When a had to do a task like said the money boubled after purchase was done in the temperary website but with some computer work the amount that was doubled disappeared. Telling me I made an error wanting more to be placed into a different account again to correct my mistake. Nothing was done have a lot of evidence and they used one person's account more than once. Mailed Grin just to get its one of there agents that gives temp codes but none was done about pay back or anything.
