Totally agree with what almost everyone here has said. My gut reaction to this if it was me, is run like the wind. The upfront documentation is onerous, taking credit card details (which is not safe to do) and not accepting other payment methods very unreasonable. Taking calls during a session and not making up for it in some way smacks of bad boundaries and a lack of respect. And this is only the beginning, it doesn't bode well going forward. I think you'd be better off finding another therapist, and I'm not saying this lightly.
