Token money of 50k forfeited

I had booked a place to rent in Bangalore in the month of May, 2020 by giving 10k advance. And was planning to move in as early as possible. Because of the lockdown, I couldn't move until June and it was decided that we will get the place by 1st Aug. Due to some personal emergency, I had to come back to my hometown(Lucknow) in June but had planned to go back to Bangalore by July end. As June end came, my owner started pressuring that either give me some more money or I will take another tenant. I gave him another 40k on 26th June with the view of moving in by 1st Aug. In the first week of July, Covid cases in Bangalore started rising and hence made it impossible for me to comeback since I didn't want to risk my health. I informed my owner on 9th July that moving in by 1st Aug will be a problem, hence you can go ahead and find a tenant. He agreed. I helped him find various tenants through different sites but couldn't find anyone. Now he says he will cut my one month rent and give me the rest 15k only out of the 50k. This is without any rental agreement and a 21 day prior notice as well. I am already paying rent of 13k to my previous owner where all my belongings are kept. So, there is no way I can lose this 35k.
