There are those reading this list who may see a payment of one of the following three amounts either to the Croydon Park Hotel in Croydon, Surrey or to the Swallow St. George Hotel in Harrogate, Yorkshire.
If so, do not panic.As this article explains, it's a screwup
. The payment is going to Blizzard, it's for your WoW subscription, and it's apparently just that the payee is mislabelled.
(I'd still check with the credit card company, but it appears that it's not been skimmed.)
