Company mentioned incorrect LWD and is asking for money in FNF settlement

I joined a company on 3rd October. After 2 days, I decided to leave on 5th October by submitting my assets at the company office. I had sent a mail stating that I could not complete the joining process. I have proof of receipt of the assets by the company, which was sent to my personal email on 5th October.

I have now received a mail where they have mentioned my last working day as 11th November. They have created a PF account and have added a contribution for October month. They are now asking money totalling 1.5 lakhs in the FNF settlement which includes the first month salary and the joining bonus. They have even created the payslip for the October month. I do not want any relieving letter or experience letter from them

What should I do in this case. Please help me out 🙏🙏🙏🙏
