Dear I remain hopeful that your agency can assist me rectifying at least two billing errors from XXXX. I have been in a four-year battle to clear this matter with XXXX XXXX XXXX XXXX ; XXXX XXXX including disputing with Wakefield collection agency~ to no avail, now this matter is negatively affecting my credit. 
I am seeking remedy to two billing errors by XXXX XXXX XXXX XXXX ; XXXX XXXX : I had XXXX XXXX Insurance on XX/XX/XXXX XXXX XXXX  billed the wrong policy # ( Also noting-XXXX XXXX did not answer initial calls or opportunities to provide coverage per my policy ). 
Please find incident information below & amp ; my continued efforts to resolve. 
On XX/XX/XXXX I went to the emergency room at XXXX XXXX XXXX XXXX XXXX XXXXXX/XX/XXXX( due to falling down 8 steps & amp ; hitting my XXXX on the concrete basement floor ) XXXX XXXX XXXX XXXX XXXX XXXX  XXXX IN ER Staff did tests & amp ; assessments : Diagnosis : XXXX XXXX & amp ; & quot ; XXXX XXXX XXXX XXXX & quot ; requiring aXX/XX/XXXX immediately. ( All treatment covered by my insurance XXXX XXXX ). 
XXXX XXXX XXXX XXXX XXXX XXXX  XXXX did not have a XX/XX/XXXX on staff/available. 
o XXXX XXXX XXXX XXXX XXXX XXXX ER staff XXXX XXXX XXXX, XXXX called XX/XX/XXXX to set up transfer to XXXX XXXX XXXX XXXX at XXXX spoke to XXXX ( per gathered ED Notes ). ( All treatment covered by my insurance XXXX  XXXX XXXX o I was transported by XX/XX/XXXXXX/XX/XXXX IN to XXXX XXXX XXXX in XXXX XXXX IN. This was a medical decision made by the XXXX XXXX XXXX XXXX XXXX  XXXX staff-I was incapable of making any decisions. ( XXXXXX/XX/XXXX transport Billed the wrong XXXX XXXX  policy #, hence it was NOT billed properly & amp ; was NOT paid-see additional information below ). 
XXXX XXXX XXXX in XXXX XXXX IN. Placed in ICU further treatment followed ( All treatment covered by my insurance XXXX XXXX ) My Dispute clarification : I was not capable of making decisions on XX/XX/XXXX & amp ; was transported by XXXX XXXXXX/XX/XXXXof IN XXXX XXXX XXXX XXXX in XXXX XXXX  IN. ( This was a medical decision made by the XXXX XXXX XXXX XXXX XXXX XXXX staff-I was incapable of making any decisions. ) My Ambulance bill was not paid, yet every other Medical Bill from this incident was paid by my XXXX XXXX insurance regarding this incident/claim ( other medical treatment was billed to the proper XXXX XXXX  Policy # ). 
It was learned in my research that XXXX XXXX had billed the wrong XXXX XXXX policy # and had already sent my account to Wakefield for collection ( prior to realizing they had the wrong insurance policy # per XXXX & amp ; XXXX of XXXX XXXX on XX/XX/XXXX ) XX/XX/XXXX Filed a Wakefield Dispute online stating successfully submitted for processing. 
XX/XX/XXXX Per conversation with XXXX XXXX Wakefield Accountant Representative the original dispute was not received. Re-filed another dispute online XXXX-successfully submitted for processing. 
Shortly after filing the second dispute, it was denied & amp ; I have once again started to receive letters of collection.
