Compensation from a person/family who hided his mental insanity and illiteracy

Hi , I was married in june,2018..I am from a christian family and my marriage was arranged..They fixed the engagement and marriage in a hurry saying that he is working abroad and has to go back immediately after the marriage giving us no time for arranging some money which leaded us to take loan from the bank..My mother didn’t want to drop this affair as they seemed to be a reputed family.. But I didn’t get a chance to talk with him before marriage as his mother said they don’t like that before marriage..They have said he have a diploma in ITI…He seemed to be very shy and socially withdrawed during the engagement and marriage day..As i am a nurse immediately after the marriage I came to know that he is mentally unstable and apart from that he was not literate or neither he was employed in abroad..From the neighbours i got to know that he was not been to school after 5 th standard ..He was with his brother in Dubai ,who was doing a business there which can make others to think like he is working and so that is mentally stable..Also when i checked his passport i have seen the date of arrival in india as 1 year ago..He was sent to home by his brother from Dubai due to his mental illness and related behaviour ..Also he can not talk clearly and can’t read or write anything even in Malayalam..These all things were unknown to me..I haven’t stayed with him for long or the marriage was not consummated as he was having erectile dysfunction..He harmed me physically and mentally and also his sister.. I had filed a petition for nullifying marriage and the marriage was declared as void.(they were being exparty).But at the time I hadn’t file petition for compensation for cheating..Now the case is in the family court..(filed in 2021)But they are not appearing for the mediation..I think it may take long..I would like to know if there’s any other section for filing this case..They have cheated us on every aspect of his son’s abilities..Is there any way i can get a compensation or can get them punished for this cruelty..Looking forward to your valuable response..
