Kesari tours and travels - Tour refund

With reference to our Kailash Manasarovar Yatra booking OK******/* for two passengers - Sripriya Rajan and Parthasarathy Kothandan in July ****.
Our tour got cancelled due to the pandemic and we received the Credit Shell Certificate dated **th Sept ****, with reference no. OK ****** and the contents there off.
As you may be aware, we have also gone through lot of hardship with loss of job, income, unplanned medical expenses due to Covid-** and there by having an economic turmoil in our own family.
We are surprised to note that Force Majeure clause is being referred. When we were booking for the trip, there was no such clause in the Terms & Conditions stated. Now invoking Force Majeure Clause and holding back Rs. **,***/ per person as re-scheduling charges is highly unacceptable.
In our case, as we booked for * pax (I & my husband) for the Kailash Manasarovar trip, the nett. impact is Rs. **,***/-.
Please note the rescheduling charges **% of the advance amount per pax is extremely high. As Kesari Tours is getting all refunds from the airlines and hotel bookings etc ; they should bear the impact and charge a minimum reasonable amount and not **% of the booking charge.
We appreciate the efforts by Kesari Tours Pvt. Ltd., Mumbai, to organize the Kailash Manasarovar tour.
We were constantly coordinating with Mr. Sachin Bora the trip organiser and were assured by him that being regular travelers with Kesari we will not be charged or penalized for such unforseen circumstances. This deduction was never discussed and agreed upon during our discussions.
Hence please provide the Credit Shell Certificate for the entire amount of Rs. **,***/- per pax, for our booking which will be Rs. **,***/-.
