It is common practice with some gas stations to place a hold on debit cards for $1-$100 until the actual debit is completed, depending on the policy of the merchant.  EECU is not able to release or dispute pre-authorization holds that merchants place on debit cards. The good news is that pre-authorization holds do not result in a real charge; they are just a temporary. The amount that is debited from your account is the amount shown on your receipt.
