A friend of mine has posted many wrong things about me on facebook

On my guarantee Mr. X (i.e., my friend) had given a hand loan of rs.50,000 to Mr. Y who is also my friend and I had given my cheque as security to Mr. X, but Mr. Y could not pay it on time and I had Rs.8500 which I paid through google pay to Mr. X, but Mr. X did not agree as he wanted the whole amount to be cleared and because of this he started threatening that he would call all my relatives for which I have a call recording of the same. and later on he has posted on facebook stating many false allegations like I am into illegal business of gambling and drugs and he has claimed that I have to pay him rs.1,90,000/- where as I have to just pay him 41,500/-, so let me explain how he has claimed the figure of 1,90,000/- that is because as he was a good friend of mine a few month ago he had come near my office stating that he did not carry his debit card and he needs to withdraw some funds so he asked me if he can transfer me and if i could withdraw from my ATM card and give it to which i agreed, he has done this twice once was rs.90,000 and next time it was 60,000. but I have a call recording in which he has clearly said that he is purposely making claims of false amount to damage my reputation and that the amount is only 50,000 but now he will legally claim for 1,90,000/- and he has posted on facebook with my photo my phone number and my office address and the same he has sent to all my relatives approx 30-40 relatives personally through whatsapp and face book. Kindly help me with what legal action can be taken and are call recordings accepted as proof in the court
