State Bank Of India [SBI] — Charging me Unnecessary charge and not giving clearance even after paying my credit card bill

So I have Submitted my Credit Card bill in one Short on 21st july 2020. I have also verification letter from your agent for the payment. But your bank didn't have clear my due as yet even after paying full payment and having verification letter. Also your bank charged me many charges for it and affected my cibil score because of it. My business is already in loss and due to this issue I am facing more issues in my life. I am doing job now at an electric shop and I can't give anymore charges to your bank for this error from your bank side. There were two members named Karan Singh whose contact no. [protected] and Isha whose contact no. [protected] who collected my payments from me in hand and handed over me a receipt vide receipt no. DEL[protected] and told me that your due will be clear soon after taking payment from me. So I request you please solve this issue as soon as possible because it is effecting my cibil score and charging me unnecessary charge for it and Provide me NOC for this. Also if possible please take strict action against those who have not updated your bank about my payment receipt even after taking money from me. Also I am attaching the letter which is handed over to me by your bank agents at the time of payment. Please have a look at it in attachment attached with this mail. Please provide me NOC as soon as possible for it, it's an humble request from you.
