Landlord cheated me

I took a flat at a rent of 12500 and advance of 70K. Since I do not have 70K with me, I requested them that I pay 60K at once and remaining 10K along with the next two months rent. The same was written in the rental agreement. I paid 5K along with the first month rent and next 5K along with the next month's rent. Actually I had an agreement for 11 months lease, After the lease is expired, I did not ask for renewal and owner as well did not informed me. I continued to pay the same rent 12500 from the 12th month onwards. While vacating the house after 24 months, they cheated me as below. 1) they told that I did not given 10K advance at all. As the did not accept online transfer, I used to pay through cash. I left with no proof. ( This type of cheating I never seen. I argued with them bud they are not agreed. I felt so bad and I got tears on my eyes, I always be good with others, but when I come across this situvation, I couldn't able to control myself ) 2) they calculated 10% extra on my rent from 12th month onwards and deducted the amount from security deposit. my question is rental agreement is not renewed, then how they will charge 10% extra. Whose responsibility to renew the agreement? 3) They deducted one month rent for painting charges. Over all they showed the amount for 62000 and in return they asked me 2000. I have never seen this kind of cheating landlords. Spent many sleepless nights thinking about this in mind. We came from a middle class family. For us even a single rupee is countable. Couldn't able to digest this, now I am even typing this message with tears. 1) They did not give rent receipts for me, and the did not given their Pan card for my tax proof submission. I am sure that it is black money. Can I complain to income tax department about them. I want to take revenge on them, please help
