Metamask double charging

Hi, I registered newly and metamask charged two failed “Register with Config” payments of 0.0056246 ETH without repaying even though it stated failed and . So my registration was at least 30 $ too expensive. Where to complain, what to do?
Thanks for any help

Unfortunately that lost gas just went to the miners of the Ethereum network, so you won’t be able to get that back.

One thing that I always recommend to people is to always cross-check your transactions in an explorer like Etherscan and verify that the transaction finishes before confirming any further transactions. That way you’ll be less likely to send duplicate transactions because of some UI bug in Metamask.


ok, thanks for the explication.
