In late 2019 I was a patient of yours for a brief while. I do not remember why (probably due to your insane pricing), but at one point I had cancelled an appointment. Since then and for the past 2 years, I have been getting billing letters in the mail! It appears you have charged me for that cancelled appointment. Getting these letters every other week is INCREDIBLY ANNOYING. I do not owe you anything! I had cancelled the appointment ahead, hence I don't need to pay for it. Please fix this in your records. I do not want to get these letter ever again!!! Thank you.
