I served a company for 7 months and resigned during my notice period. I had 10 Paid Leaves and 5 Sick Leaves for the year. After 4 months of service, I took 10 leaves approved by my manager. Now, a month after my last working day, they are asking me to pay for the extra 5 days of leave I took beyond my allotted amount. They are considering 5 leaves as per pro-rata since I served only 7 months. This was not mentioned in their policy or offer letter, and I was not informed when I resigned or on my last day. They did not provide me with a relieving letter. If they had informed me when I took the leave, I would have adjusted my leaves. Please suggest.
