(((Useless Me))) I think I would start at the receptionist to see if you have a receipt there. To keep track of the money that is received by your therapist office they have to be able to keep track of the money some way. Weather you are at the desk or not. If there is not a receipt there then I would ask the billing department. If the money has not showed up in the billing department I would have my therapist look into it for me. In My Case - I would also have to check my own pockets - depression keeps me confused 90% of the time. If the money does not show up I would make a complaint. Maybe your therapist can help you with this also. Just have to make sure the money is gone before you ruin the receptionists character.
