Losing my gold at auctions

good afternoon my name is dayler I want to ask you a favor, I would like a solution to my situation, I lost in an auction 8k.
I was buying cobalt ingots, I bought them per unit and it turns out that when you buy they are removed from the list of purchases and raise other bids, but in my case there was a delay I accepted the 2g but the last one was an 8k and when I looked I had no gold please I can attach a photo or something if you want, I ask you to make me a rollback of a few minutes just spent about 15 minutes please, I think the list was modified by making more than 3 purchases in a row, I would like some solution please.
