Strange credits from poker sites appearing in friends bank account

[sarahbellum]

This is a new one to me. A friend of mine (seriously, a friend) used to make deposits onto poker sites using either her credit card or via EFT from her checking account. She says the only sites she's played on are FT, UB, and Stars. Suddenly she is now receiving credits back onto her credit card and into her checking account. She has done nothing to initiate these credits. She hasn't generated withdrawals. She also can no longer make deposits via CC or EFT due to them no longer being allowed by the financial institutions.

She is not 100% certain where this money is coming from or why she is receiving the money. There are two names on her statements: Southvale Compass SE and Port Louis. The credits are in even dollar amounts (100, 50, etc). The dollar value is approaching $2,000 at this point. She has not yet logged onto her poker accounts to check the transaction logs.

Like I said, she didn't initiate these withdrawals. No one owes her this money. She's not complaining. But we're both curious as to what the heck is going on and why someone is refunding this money to her. Are the banks doing chargebacks to the sites on deposits made via CC/EFT after a certain date? Ideas, anyone?
