I started to go with E-Trade when the DL promo first came out. Just happened to get a large expense reimbursement check that would have worked great for the 50K miles.
I signed up for an account on line, but had a question about how they make a market for foreign stock. I e-mailed the question to them at the address they have for questions, and waited to hear back from them before I sent in the money or the forms.
Almost 6 weeks later I got an automated response saying there was possibly the e-mail I sent may not have been read. If this was the case please send it again. Oh yeah, like I am going to do that, trust people to handle my finances who don't know if they have read and replied to my e-mails or in fact don't read and reply to my e-mails. Fired before they were hired.
By the by, about 5 months later received a letter asking for my social security number as they needed the info to finish processing my accounts.
