Lincoln cancelled my benefits because my doctor's notes were handwritten

I have been on a short term disability since June of 2020. I was paid additional benefits through Lincoln Financial after SDI paid me. In august of 2020, Lincoln Financial sent an email stating they didn’t receive dr notes of my visits. I reached out to my doctor to see if they could send those notes to ensure benefits wouldn’t be denied. The doctor office sent over multiple faxes and emails and Lincoln claimed they weren’t receiving them. After speaking to Shawn Ransom at Lincoln, I explained that my case manager was very rude and wouldn’t return calls back. Shawn was helpful and said he would get another case manager to help me out. Doctor notes were resent from my Dr’s office and this time they said that the doctor notes weren’t legible and they asked the doctor if he could type up doctor notes. Doctor refused and said he has never been asked to type notes. Lincoln said I wouldn’t get paid benefits from August 2020 to current if he wasn’t able to type the notes. Received a call from new case manager Brittany, stating they denied the appeal because doctor never sent over legible notes. I am so unhappy and I have been behind on car payments, and other bills that are piling up. I requested another appeal and will wait to hear back from Lincoln. I have read Better Business Bureau complaints online, about how horrible Lincoln Financial has handled their short term disability claims and similar bad experiences with the doctor note situation. I am off work due to depression/stress and they haven’t helped one bit. I am looking into an attorney about this.
