I would start by contacting your card vendor,if the charge has been made and should not of been then they may be able to reimburse and follow it up to reclaim it.If your spyware will not let you on the site how did you initially get to it ??? Why do you want to get back on the site,altnet is known spyware and the site you have used is most likely malicious and will most likely make things worse.this is one of the pitfalls in the learning curve of such things as filesharing,is it really worth it ?? most likely not,thousands of people get ripped off everyday with such scams,hopefully once bitten and twice shy.
