No zero or negative star is possible…otherwise they would deserve..Scam, scam..they only send the free sample if not canceled within the test period…and if not canceled they charge you the second month..The cancelation is quite irregular and contract is supported by many ilegal contractual termsTheir customer service keeps treatning with debt recovery service unless you pay for the scan…hilarious…I wounder how many poor people they need to trick for the scam to be profitable?!Shame..shame..shame..
