My child was seen for dental care in August 2021. I did not get the current bill for this until roughly March 2023. I called billing on 2/28/2023 and the **** ******** could not locate the invoice I received. She checked by multiple accounts, patient name, dob, location, provider. She could not locate what I was looking at and was going to call me back. Without a return call, and this being a previously paid invoice (which I can no longer look up on any of my accounts due to it being over 18 months ago) not matching my EOB, and there being previous unresolved issues with the office, I believed this invoice to be a scam. I received another invoice, called again, but couldn't get through the same number from the invoice, from 3 different phone lines. I found another number online and spoke to ***** at the corporate number on 3/27. She said there was a billing system switch and that is why invoices were going out 18 months later. She was going to look into this with the office manager and call back. I haven't heard back. I emailed corporate through their website on 4/11 asking to email me to resolve further. I just want to resolve this. I wanted to resolve the original service issues I had back in 2021 with the managers behavior, statements they made and supposed cancelations of appointments that i never rececied and showed up to, but corporate never called me then either, so I moved on with my child to find another dental provider. At this time, I need this adjusted off. My experience with office management and billing practices have made this a bad customer experience and my child terrified of the dentist. Calling is best for resolution but email is fine also. Thank you!
