I received a free voucher from my web hosting team and when i tried to login its says : The page you requested is invalid. I sign up for new account and receive same error. Should i contact GMAIL for this.
I don't know why dd you say this "Should i contact GMAIL for this"? The free voucher was sent by your web hosting not by Gmail so you should contact to your web hosting team as the error is page you requested is invalid and it comes when the page is not present or it is removed temporarily.
