Dear Sir/Madam, I am writing to follow up on my previous complaint regarding the denial of my insurance coverage under the policy I purchased from One Main Assurance Services LLC , administered by XXXX XXXX and XXXX XXXX XXXX XXXX XXXXXXXX XXXX XXXXXXXX XXXX My name is XXXX XXXX, and my claim number is XXXX. 
I would like to bring to your attention the inconsistencies in the records request made by your company. On XX/XX/XXXX, One Main Solutions sent a letter requesting medical records from XXXX XXXX XXXX XXXX, which were promptly provided to your company during the same month. Subsequently, on XX/XX/XXXX, you requested records from my primary doctor, XXXX XXXX, for the period from XX/XX/XXXX to XX/XX/XXXX. 
To facilitate the retrieval of these records, I arranged a third-party call with your representative, during which the necessary medical records from XXXX XXXX were transmitted. This call was meant to ensure the seamless submission of the requested documents and avoid any delays in the claim review process. 
Despite the timely provision of the requested medical records from both XXXX XXXX XXXX XXXX and XXXX XXXX, I have yet to receive any confirmation of receipt or updates on the inclusion of these records in the evaluation of my claim. This lack of transparency and communication is deeply concerning and hinders the progress of resolving this matter. 
Therefore, I strongly urge you to expedite the review of all the records that have been submitted, including those from XXXX XXXX XXXX XXXX and XXXX XXXX. It is imperative that you thoroughly assess all the relevant information to make a fair and accurate determination of my claim for insurance coverage during my medical leave of absence. 
Furthermore, I reiterate my request for prompt payment of the benefits owed to me for the period I was on medical leave. The purpose of this insurance policy is to provide financial protection during such circumstances, and I trust that you will fulfill your obligations accordingly. 
I once again request immediate and effective communication from your company. It is essential that someone contacts me without delay to provide updates on the status of my claim and address the concerns I have raised in my previous correspondences. Additionally, I reiterate my request for the contact information of the Office of the President to ensure that my case receives the attention it warrants. 
If I do not receive a satisfactory resolution within [ reasonable timeframe, e.g., 14 days ] from the date of this letter, I will be left with no choice but to escalate this matter to the appropriate regulatory authorities and seek legal remedies to protect my rights as an insured individual. 
Once again, I have attached copies of all the relevant documents previously submitted for your reference. If any additional information or documentation is required, please do not hesitate to contact me at the phone number or email address provided above. 
I expect your immediate attention to this matter, along with a prompt resolution that upholds the principles of fairness and transparency. Thank you for your immediate action. 
Yours sincerely, [ Your Name ] XXXX
