Hate that you're having these difficulties @namutravel. I've just set up my 2nd business on Square and can say the bank account connection did not need a debit card to complete the process. Unfortunately, your issues may not be something we can help with other than to say double-check each item along the way. I'll be setting up a third business in a couple days. I'll pay close attention to the bank account setup and check back to see if I can be of assistance if you haven't already gotten to the bottom of it.
Take care of yourself and, as life provides, someone else too.
