if you cancelled without proper notice you fucked them over. that's what they were projected to make that day through insurance and you deprived them of finding a patient to take your place.  give plenty of notice or cancel any plans to make it to your appointment. you are an adult, act like it. also go sign up for medicaid , its easy and pretty much free healthcare if you are in an in network area with many providers.  no excuses, you sound kinda slow
