I had a collection on my credit report for a certain phone company (Sprint) who sold it to Diversified Adjustment Services. I cancelled my phones due to my payments where never getting posted to my account and they kept charging me. I paid off "What I owed" but they say i owed more. So i refused to pay for what I don't owe. I owned up to the debt but refused to pay for what they added on to my account. After about a year, they begin to delete the Collections from my report. What does this mean , they can afford to keep reporting it, they sold it again, or what.
