Two Plus Two Older Archives - Absolute Poker Cashier Mistake?

I was three tabling and bought in for the minimum - just signed up and wanted to test how the games were on the 1/2, 2/4, 3/6 holdem tables. After a while, on 2 of the tables I was slightly below the minimum buy in, and I figured what the hell, let me add more. One was successful but the other one didn't work initially. I checked my bank and nothing changed. I tried again and still no go, however, I checked my bank and money was deducted. Given it was only $12.50, but anyway I can do my own digging to find out if I was accidently robbed of $12.50? I emailed Absolute immediately after the incident occured and haven't heard back yet (it's been 2 days). Oh well, just curious. I'm not really steaming over $12.50. Thanks.
