Annual leave policy

I had 35 days annual leave balance as on March 2020 and my company said you cannot carry forward more than 6 leaves so you need to apply for 29 days leave. They never paid that leave but asked us to take when companies open after lockdown. We never got a chance to go back to office and we were working from home. Now I am asking them to give me those leaves or pay me but they are saying you can carry forward. Can someone through a light on this
As per the leave policy it says " Annual leave can be accrued to a maximum of 45 days at any given time. Only upto 6 days per year can be carried forward for accrual ".
