Ive never had to call them but thats a joke. I hope all webmasters realise that the websites have to operational offline as well to be taken serious. Its a pet peeve of mine.
It will be better if they list the support phone line. Don't understand why they didn't list it in spite of being such a large company!
Ye, I couldn't find it anywhere either. I found out the number by looking at my bank statement. ClickBank is too big to not have the phone number listed on their site. I agree that they should include it.
