Complaint sub-issue: Difficulty submitting a dispute or getting information about a dispute over the phone

I have a invalid entries that was placed on my credit report and I have been trying for over 12 months to get this entry removed. I have spoken with numbers representatives, supervisors, and managers in regards to the erroneous public record and I have yet to get it resolved. This is my 14th dispute in which I am currently awaiting results. On XX/XX/XXXX, I called and spoke with a representative and inquired how Equifax, XXXX  and XXXX  verifies their negative accounts. I want to know this information because these accounts keeps coming back as mine. I had 20 representatives that told me that the request/dispute is sent as a message to the courthouse through eOscar. Once the court verifies it, the information is sent back to the credit bureau. I advised that I would like to cancel that dispute and they advised that because the dispute was already sent to the courthouse, I will need to contact them with my name and the case number. Being that I work for a XXXX XXXX, I know the court system and their procedures, but decided to call anyway. Contacted the court and they advised that they do no disclose, release or verify any information with the credit bureaus or any 3rd parties. I decided to call Equifax back, spoke with another rep this time and they advised that the information is verified by the runner who goes to the court house. I asked what information does the runner give to the courthouse, and how and what kind of physical information does the runner give back to the credit bureau. They could not answer that, and I requested to speak with the manager. Manager advised since this is a re-investigation, no runner is involved. She advised that they use a form that they send over to the courthouse. I asked what type of form and where is it sent because the courthouse confirmed that they do not verify any information with the bureaus. All XXXX major bureaus refuses to give my physical documentation ( whether tangible or electronic ) that they use to verify this these accounts are mine. I have contact all involved parties the credit bureaus and companies to have accounts removed ; provided proof of payment and payment history. Proof is also attached to this complaint.Bureuas are also disregarding letters received stating that " it appears that letters aren't coming from me '' requesting more identification information which is the information that was including in letter a picture ID, Social Security Card and Utility Bill ; this practice is a stall tact to again not process letters or removing invalidly reporting entries on my credit. I keep getting the same feedback when I am submitting the correct current requested documents. been contacting the credit bureaus for 12 months via letters mailed in/fax/ and over the phone ; they are returning letters back to me ; refusing to investigate a lot of letters and fax went unacknowledged on letters that were sent certified mail so have confirmation that they have received them however when call rep states no record of receipt. I am fully aware they are backed up and working from home I hear family/pets in background systems go down while on the phone. This is clearly unfair that representatives are able to work from home, not held to office compliance, and refusing to process files that are received. No formal investigation is being engaged ; totally understand that we are in a pandemic however the world doesn't give agencies to be able to disregard work load and properly process files ; no laws have been sat in place to extend/amend investigation process and we are entitled to fair due process and letters to be processed without delay. WILLING TO SUBMITTED ENVELOPES THAT SHOWS " RETURN TO SENDER. INVESTIGATION ARE TAKING LONGER THAN 45 BUSINESS DAYS!! Bureuas are also disregarding letters received stating that " it appears that letters aren't coming from me '' requesting more identification information which is the information that was including in letter a picture ID, Social Security Card and Utility Bill ; this practice is a stall tact to again not process letters or removing invalidly reporting entries on my credit. I keep getting the same feedback when I am submitting the correct current requested documents.
