Cosmeo Bad Business

Cosmeo has made it very difficult to cancel and do not include their phone number on their website although they require you to call their phone number to cancel. If you click on the "contact us" link, you go directly to email. After a month, someone emails you back and says for security purposes you have to call. What type of security problems could a kids homework help website have that would require this? I paid for several months of this service that I did not even need or use and they refuse to give any type of refund although I have emailed them twice to cancel. Once you are logged in you can get a phone number but there is no mention of that after scouring their website for a phone number. Nasty Nasty Discovery Channel!
