That patients can schedule 4 sessions in advance (to reserve their schedule) BUT that they MUST and automatically have to pay one week in advance for their next appointment, otherwise they miss it. Now you can but you would have to pay for all 4 immediately or else, you would have to pay none and it's okay (automatically) if you don't pay and arrive at the session without payment (You have to tell him, you have to leave the session paid). What I'm looking for is that you pay for the nearest session OBLIGATORILY, otherwise it will be deleted... but that you can schedule 4 or 8 sessions per shot. Is it understood??? If not, please contact me (+569 3878 0845)
