No notice of debt was ever sent to me regarding a debt dated XX/XX/XXXX. I have also never received a medical bill from the durable medical equipment provider, XXXX XXXX XXXX in XXXX, XXXX I was told that XXXX does the billing for this XXXX provider ( never received a bill from them ) and XXXX third party collections agencies are used. At the time of service, I was dual insured with XXXX XXXX XXXX XXXX XXXX, so there would be zero out of pocket cost. I spoke with the XXXX provider & was referred to XXXX. XXXX informed me that it was turned over to collections XX/XX/XXXX. I never received anything in writing from the XXXX XXXX XXXX XXXX, XXXX ). XXXX claims to have received a " cease & desist '' from me XX/XX/XXXX which I never sent them. I never spoke with anyone or had any contact with this debt collector. On XX/XX/XXXX, the account was turned over to another collection agency, Northland Group XXXX XXXX XXXX, who claims to have sent debt letters to me and has left numerous phone messages. I have not received anything from this collection agency either. I am disputing the claimed debt. Northland Group then closed the account XX/XX/XXXX with " efforts exhausted '' & then reported me to the credit bureaus. I am also complaining about the fraudulent methods that both collection agencies have used. Furthermore, the XXXX provider has provided me equipment every 90 days over the last 2 years and has never told me there is an outstanding balance. The dates of service reported/billed are every 60ish days and I only got XXXX every 90+ days. XXXX ( XXXX XXXX XXXX XXXX XXXX, XXXX XXXX, KS XXXX, XXXX ), XXXX XXXX XXXX, & their collection agencies all have my correct/current contact information. Now I am being denied medical care and they are the only XXXX that has the medical equipment I require.
