Product: Debt collection

I am receiving collections phone calls when I have a {$10000.00} credit in my name. I should owe no money to any medical as I received {$10000.00} in an account for Co-pay assistance for XXXX  and reached 100 % on my health insurance early in XXXX. 
XXXX XXXX was enrolled in the XXXX XXXX-Pay assistance program ( XXXXXXXX XXXX XXXXXXXX ) All monthly bills were sent XX/XX/XXXX according to XXXX at XXXX XX/XX/XXXX {$10000.00} was placed in a fund with my name. Contacts included XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX at XXXX assured me month after month that her records showed I was paid up 100 % My husband and I have been receiving harassing phone calls repeatedly from an anonymous numbers. We do not pick up unknown or anonymous numbers. We live in Alaska so often these calls have been as early as XXXX in the morning disrupting our sleep, repeatedly throughout the week. These sleep disrupting repeat phone calls have added to our high stress level. Several times when we did pick up the call on the old phone with no phone id we asked who was calling and learned it was from a company called Miramed, a collection company. 
Miramed will not discuss the account except to arrange payment, which I do not owe. No one will transfer me to a manager or other person that has any decision making authority. No contact phone numbers or address for additional help was given. 
A little history, on XX/XX/XXXX I wrote an email to XXXX requesting assistance. We did not hear back. 
Saturday XXXX XXXX. I picked up the phone upstairs, it is a landline that does not show who called. The toll free number was said so fast you can not write the number down. I pressed one and asked what the number was XXXX XXXX XXXX, what company was calling? MiraMed and to please spell it. What does this company do? Accounts receivable Management in XXXX, Illinois. 

I do not owe this alleged debt. I had in XXXX a {$10000.00} XXXX  credit on account for the XXXX XXXX-Pay assistance XXXX  and reached 100 % coverage on health insurance early XXXX due to XXXXXXXX XXXX at the hospital XXXX XXXX. The contact person is XXXX XXXX XXXX XXXX and contact information is XXXX XXXX XXXX. The XXXX XXXX-Pay Assistance program XXXX XXXX ( XXXX ) I have provided this information to employees several times starting XX/XX/XXXX. They refuse to accept the information, and refuse to provide contact information to reach someone who is empowered to act on this information. XXXX at XXXX assured me month after month that I was covered 100 %. 
I received a form letter regarding an alleged debt. I responded immediately in XXXX in writing disputing this inaccurate, erroneous debt. I responded with a letter disputing the debt and provided information relating to a {$10000.00} XXXX  on account with Co-pay assistance with XXXX on XX/XX/XXXX XXXX at XXXX XXXX XXXX XXXX XXXX XXXX. MiraMed did not respond. I never received verification of the debt from MiraMed. MiraMed has been and continues to be ; unprofessional and violate my rights under FDCA by illegally harassing me by calling before XXXX. I informed them I live in Alaska explain the time differences. I have asked repeatedly for them to stop doing so, and to stop calling multiple times in a row. The robo caller talks so fast as to be not understandable. I have been hung up on several times. I asked for a written statement from them. She refused. I am continually asked for personal information, which I will not provide. Messages are too fast to get contact information and the employees are not clear when speaking. Asking for repetitions elicits anger, hang ups, but never, clear information. Callers refused to give information about contacting MiraMed on several occasions. I advised callers several times that they were not understandable and to make contact by mail or provide me with information for contacting MiraMed by mail. Anonymous calls persist at XXXX repeatedly even on weekends. MiraMed blatantly violated my consumer rights and continues to do so. This alleged debt lacks veracity and verification. 
Please assist me in this matter. There should be no need for the use of an Accounts receivable management company as all medical bills should have been paid by a XXXX for deductible/copay & /or covered by XXXX XXXX insurance XXXX Any credit rating impacts should be rectified. 
Thank you for your support.
