You need to get evidence of the funds going out of your account an the issue with the gambling site, you need to prove why you haven't received them. Even if it's a different merchant to bypass gamstops they won't pay you because they see it as the service was still provided
IMO. Telling them its gambling related it's the best course of action, it's being honest, rather than a blag. Often the merchants won't be licensed to operate in such financial matters. This is evidence you need to collate. You need alot of evidence when you go down the path of telling them its gambling related. 1. Because they see you as an immediate liability in that sense so you need to evidence everything.
Many others have lots of success with the good not received for what ever they are disputing ect. For me I can give them alot more evidence of wrong doing if there has been foul play that I can prove an there is a reason to why I'm disputing.
MasterCard are more stringent than visa when it comes to disputes.
Well, so I've found anyways
