Reliance General Insurance — I am complaining about not resolving my health claim no.[protected]

Sir,
I have submitted my all the required documents on Dt.02/09/2021 by email. But your company is repeatedly sending me mails to submit documents. I had confirmed that the company has already received the documets on Dt.03/09/2021 through calling your customer care. But, after 19 days of receipt of documents, the company is sending me mails and self-i app is also displaying "Documents are pending".
Please do needful in this matter
