It's a collection agency. When you answer they ask you told hold while they connect you, but never explain who they are despite telling them to state who they are or your not holding, then all of the sudden your transferred to another representative who barely speaks English. After they connect they try to verify who you are by asking your name, address, and social security number but still do not disclosing who they are,reminder to never give out your information especially when you have no clue who they are. There are too many scams these days and billions of people fall for them. Anyway, After asking them 9 times to identify themselves,I finally got that they were calling to collect on a medical bill from A1 Imaging. They said they've called 151 times & left 151 messages, but when I asked why no paperwork /statements have been mailed he said they just got the account 2 months ago. 151 calls in 60 dash is harassment. I told them I dispute resolution debt because I've not been to an A1 Imaging place and that I wanted proof of the debt, he hung up on me. Call comes from an Orlando/Altamonte Springs area call center.
