SOTC — refund of booking amount as not able to travel due to covid 19

I had booked a holiday package with sotc for travel from 8th may till 14th may,
Trip was to sri lanka for 8 people (8 adults and 2 children aged 5 and 13).
Due to the ongoing coronavirus pandemic, travel is not possible and the same advisory has been given by the government of india.
Sotc advises me to use the booking amount for travel within the next one year time. But i do not wish to travel during that period.
I want full refund of the booking amount rs. 80000.
