The Resume Search — Blackmailing for not competing

Hi.I just find this resume search job in google so i took up that contact nd then contact them on whatsApp on before last 2month at that time they told there is no processing fees at earlier so i think to join there but after that i didn't receive any msg from them and just before 1week i got msg frm them so they asked me 1 id proof nd my mail id. Afterwards they instruct me to read the contract nd sign on it but after the reviews I viewed got some fear to put sign... But they taking our sign automatically without putting by me.. So i asked but he replied like that he called me to tell about this... Nd then I have no option so i tried to complete work but i can't do that so he answered me rudely ... I blocked him but he s messaging that blocking is not working am going to file a case on u be ready to faceoff in court like this. Am frm poor background waiting fr a better opportunity but like this type of company making me so depressed. Please help me i[censored] can
