I'm following up on the above. Without some further information from you as above, I am limited in what I can say on the matter but in the hope it is helpful nonetheless, I will provide you with the following broad answer. If you are able to kindly provide me with the above further information or if you have any further questions generally, I will be delighted to expand on the following - please just reply back to me in this case:
Notwithstanding the above, in general terms it may be difficult to recover your money if you can't recall any details about the scam. This may be the case because by definition, if you can't remember the details, it is possible it was not a scam. Also on a practical level, if you are to seek to recover monies, your credit card company will ask you for details of the reason for your dispute and you would need to be able to explain that you have not received the service that you paid for it if you have no idea what it was that you paid for, it may be difficult to explain what you haven't received.
if however you are able to recover some memory of the details even in the most basic terms, to enable you to at least be able to say that you have not received whatever was promised, then you can contact your credit card company and ask them to process a charge back in relation to the monies that have been debited from your card on the grounds that whatever service was promised to you has not been received and accordingly, the other party is in breach of contract or has commited fraud
I hope the above is of some assistance but if you have any further questions, please revert to me
