Product: Debt collection

I have had problems w/the COLLECTION AGENCY IN THE PAST. 
COLLECTION BUREAU OF THE HUDSON VALLEY. 
In XXXX 2007 i been punched in the mouth by my sibling & needed stitches. My son was going to drive me to the ER when the ambulance showed up-which i did n't call. i refused their services-as i had only had MEDICARE @ the time & ambulance did nothing for me. 
I was repeatedly sent a bill in which Medicare had paid part of it but they still wanted {$150.00}. 
I suffered a XXXX in XXXX of 2007 & was in XXXX for 3 months. Of course the bills piled up before i was even discharged. i did have a tidy amount of $ in the bank & though i was XXXXmy son would sit me up for an hour a day to make payments by credit card. I paid everyone a little something. 
Please remember i was hospitalized for 4 months. 
These " people '' CBHV came into my life again & would call all hours-not following the law. But as i was so badly injured-i never thought to report them. This had nothing to do w/the XXXX ambulance bill. 
I paid them off just to get rid of their " guerilla tactics '' as i was a very sick woman. 
Now keep in mind-my XXXX score is over XXXX! What they had done w/the original {$150.00} charge is kept changing the date of service SO IT WOULD REMAIN ON MY CREDIT REPORTS even after 7 years-in which it is SUPPOSED TO BE REMOVED. 
Now on to the current charges. After spending {$50000.00} -all the money to my name-i then applied for MEDICAID IN NYS. 
So this current charge when i was seen at XXXX XXXX Hospital, i received a bill for {$25.00}. I called billing & gave them my MEDICAID # and this was supposed to clear this charge. OR SO I WAS TOLD of {$25.00}. 
i just received a COLLECTION NOTICE from this corrupt collection agency in which it is charging me {$47.00} for an original bill of {$25.00} -again- i thought ( and was told IT was taken care of ) as due to my incredibly LOW INCOME from XXXX ; i would have qualified for the Charity Grant! 
so CBHV not only keeps reporting a {$150.00} by changing the date of service TO KEEP IT ON MY CREDIT HISTORY which obviously is not effecting it & gt ; & gt ; & gt ; IF MY XXXX IS OVER XXXX! but what THEY ARE DOING IS ILLEGAL. 
AND NOW THIS ERRONEOUS CHARGE from {$25.00} to {$47.00}. XXXX! 
I did write to them & tell them not only am i DISPUTING THIS CHARGE but knowing " their '' falsified reporting tactics-was reporting to you. 
I receive after paying MEDICARE & my MEDICAID SPENDOWN-ANOTHER ISSUE-which they are continually harassing me telling me my medical receipts are not applicable to my SPENDOWN which is incorrect as i know WHAT IS & IS N'T. 
Anyway-after paying {$100.00}? to MEDICARE & A SPENDOWN OF {$64.00} A MONTH-i am trying to live on {$830.00} a month! 
AND AS A HOMEOWNER-I PAY LAND & SCHOOL TAXES which i pay for ambulance services right in my TAX BILL! 
yes, i have REPORTED various issues here. 
But my MAIN COMPLAINT NOW IS W/ C.B.H.V who i do n't owe this money to. Certainly NOT their " arbitrary '' charge of {$47.00}! 
AND THEIR CONTINUAL CHANGING THE DATE OF SERVICE FROM 2007 AND REPORTING TO XXXX ; XXXX XXXX ; XXXX ... 
IF I DID N'T PAY MY BILLS WHY WOULD MY FICO SCORE BE SO HIGH? and due to trying to maintain a home on {$830.00} a month i live on CREDIT CARDS so my score is exceptionally HIGH. 
I AM NOT PAYING THEM FOR THEIR LIES. AND THE WAY THEY " threatened me in the past '' when i could n't even go to bathroom by myself. 
Thanks for your attention to this matter AS THIS COLLECTION AGENCY NEEDS AUDITING.
