Product: Credit reporting, credit repair services, or other personal consumer reports

On XX/XX/XXXX ( thus, in the mids of the pandemic ), I got notified through XX/XX/XXXXupdates that my credit score dropped by 100 points in one day. I went to see what happened and XXXX, the student loan lender, submitted several delinquent accounts. I tried to dispute these through all credit agencies and I called XXXX to understand what happened. After I talked to one of the XXXX  customer service representatives ( XX/XX/XXXX or so ), two days later they submitted additional " nonpayment '' information that lowered my score even further. I called XX/XX/XXXX and according to the information I submitted to them, they deleted these from my credit report. However, TransUnion and XX/XX/XXXX have only updated the information dismissing my dispute. TransUnion representatives were utterly rude and patronizing, and when I wanted to talk to their supervisor, one of the rep transferred me to another customer service rep instead. When I finally got to talk to the supervisor, he informed me that all my documentation that I sent by certified mail to their PO Box ( after I was instructed to so ), most likely would not be taken into consideration for the dispute. XX/XX/XXXX, on the other hand, I submitted all the documentation online via their portal but got unsatisfactory results and my credit score remained affected. Now, before all of this outcome with my credit score and XX/XX/XXXX, TransUnion, and XXXX of course, I need to remark the following. Since I received my XX/XX/XXXX I was on the search for jobs, but I was not getting any. I kept filling income-driven replacement plans with both XXXX XXXX XXXX with which I have been in good standing XXXX and XXXX. In XXXX, my payment for both lenders was {$0.00}. This continued throughout XXXX as well. Only once I got a bill fromXX/XX/XXXXin the amount of {$370.00}, which I could not understand because I was on the income-based repayment plan and no payments were scheduled. I addition, I was on social welfare at the time, as I proved to them through my tax returns and other supporting materials that I have been submitting to this lender ever since I defended my dissertation. Now, I have never received any of these XX/XX/XXXX bills that I see listed on my credit report - never! There are amounts from {$1.00} to {$5.00} - which I understand there are 7 accounts opened, and even I thought these were all consolidated, apparently, my documentation ( again and all over again ) did not reach their service. In addition to not receiving or not knowing anything about these " nonpayments '' until they were posted on my credit report, XXXX decided to submit these in the midst of the pandemic and the fed. student loan payment suspension ( see attached ) and after I told them that I lost a job in XXXX due to Covid19. I informed all three credit agencies about these issues, but only one was decent enough to remove these from my credit report. The other two play the corporate game of killing the poor and did not even take into consideration any of the documentation that I submitted to them. Thus, hereby, I am seeking help through the Consumer Financial Protection Bureau. Thank you for your time and consideration. 
Sincerely, XXXX XXXX
