I opened an Etrade account in March with $1000 to get 5K miles and never received the miles. I sent a complaint to Clickrewards and they are investigating but no response yet. Etrade keeps sending me different "open an account" offers and I think they are playing dumb about the miles.
Before opening the account, I called them to verify the terms and also wrote "this is the Clickrewards address" next to my e-mail address on the application form.
