Salary Full n Final Settlement

I have worked in a company for 8 months as Business Development Manager. my probation period on offer letter was 3 months, without prior notice company increased my probation period further for 3 months and then again 3 months. As it was a field job i had to travel through two wheeler and on job day i had an accident in that I broke my foot bone through those circumstances I was not able to go to office. As company has no insurance policy I could not claim any funds. I have resigned after one month of the fracture because it was hard for me to carry on through work from home. I have resigned on 14th March, 2023 and as per my probation period I served 7 days of notice period til 21st March, 2023. It has been a month after my last day of working period in probation, now Company is asking me to sell the rest products to get my full n final salary. They are forcing me to deliver it on certain locations. Please help me what can I do. I have done all the payment collection before leaving the organisation.
