This is a nasty side-effect of the SixXS code unfortunately. We didn't design it with in the back of our minds that PoPs would go down for extended periods of time. It thus happens that it will deduct credits when it notices that a tunnel is back, even though the tunnel was not offline, but the PoP was (which makes the tunnel be offline for the rest of the system). In this case credits are of course returned. See your logs for the details. We'll scan the list of other people affected by this and return their credits too.
