I get calls from them all the time. Yes they are a medical debt collector. I made the mistake of calling back cause I thought I only owed $13. No, that was just 1 bill. I paid the $13. Then they wanted 2 set up a payment plan. They already had my bank info but didn't make agree to a payment plan.Had 2 do a stop payment from my bank. Now they call constantly. Also comments they make 2 people about not wanting 2 pay our bills. That is so UNTRUE! Some of us fall on hard times.as of now I'm working on paying 2 separate collection agencies. Unfortunately I'm on disability. In my late 30s I was diagnosed with several ailments, mostly my back & neck. Scoliosis, Spinal Stenosis, degenitive disk disease, fibromyalgia, bipolar etc. I didn't know my future & this would happen. I loved my job. But anxiety & panic attacks started, bottom line, my disability check is much smaller than it would be if I retired later in life. So it pisses me off when these debt collectors cut you down & make comments about not wanting 2 pay our bills. They dont know many peoples situation. Sorry for the long comment. It just burns me up when they down people w/o knowing a persons personal problems. Its cruel, harassing etc. Plus its worse when they make threats. Ok, sorry. Done yacking.ps the # who called was 918-213-4566. ARS, Account Recovery Services or it comes up as TAB, Tulsa Adjustment Bureau.
