Senex Services Corp. Debt Collection Complaint

Senex Services Corp. Debt collection department,

Medical Disclosure verification of debt Right to dispute notice not received Hawaii

Found out that there was a debt collection for $160.00 on my credit report. I was covered by - at the time. I was never notified of the charge nor notified when it was transferred to a debt collection company. I only found out about this charge when I got - -. This charge was from 2010. I contacted SENE- Services and they have no record of it. I 'd like to pay the debt in full and request it be removed off of my Credit Score - or figure out why it was not covered by - as it should have been originally ( - informed me that I 'd need to contact the ER for billing, but the ER has no record of it either ) ... I just want this off of my credit report. It should n't be there as I was covered, I should have been notified, and I should be able to resolve this. If there is no record of this, why is it o my account?
