E*Trade Financial review: Joint brokerage account 1

I created a joint brokerage account with my wife last week on Thursday. The website stated that I would be approved in 24 hours or less. By Sunday, I still did not have access to the account to make trades, so I called. I was told that my wife needed to submit her social security card and driver's license. So, I uploaded those two documents. I called again and was told that everything looks good and I will be approved, most likely, early Monday morning. I waited until Wednesday morning to call, as I sill do not have access. I was told that my joint application had a wrong digit for the social security card number, as the application did not match the photo uploaded of my wife's ss card. He then stated that she needed to submit a w-9 to get the account approved. I asked why, isn't the photo of the ss card all you need? He didn't respond, but rather just restated that she needs to submit her w-9. I asked why again? he said he would look into it and then restated that she needs to submit her w-9, but rudely this time! Very unprofessional, as he could not provide an explanation and started yelling at me while repeating the same BS line about her w-9.
