ricky fs is banned here, they run away without any explanation or whatever..if you wanna cancel your credit card subscription make another card, is the only way..if you did transaction through paypal, read here and do the steps provided by paypal..
Good luck.
edit: paypal is banned here, lol.. just type on google " how to cancel paypay subscription...that would o the trick".
ps: if you are a downloader, i suggest you go to a private torrent tracker ( torrentday, ip torrents..) and buy a seedbox instead..
