Perder todo mi oro en subasta

good afternoon, I am Dayler I want to expose my case please I just happened to me a few moments ago, and I think it happens very often I do not know if you can make a rollback to my account about 5 minutes ago where I was buying cobalt bars about 6 different units and to make one was accepted one of an exaggerated value please do not know how I can recover all the gold that is in my mailbox purchase to be able to check the purchase, there are many prices wrongly placed in the auction and it was a mistake when I bought an object was uploaded another with a high value and I lost all my gold about 8k at least please I want to recover thanks
