Landlord Harassment — Landlord is calling me and harassing for more money

Address:

Vaishali, Ghaziabad

I have vacated house on 29 aug.. and house furniture was damaged by termites because I went to my home due to covid-19 on 15th May and on July I gave noticed to my landlord about vacating house because landlord was increasing rent. At the time of given notice I was lot aware that house furniture is damaged by termites still I gave 10000 as compensation to my landlord for the furniture damage but now they asking for more money and calling me and saying if I dnt pay full amount of repair of furniture they will lodge a police complaint or sue me. I am very much depressed and tensioned because of this. Please suggest me what should I do.
