Fraud activity from a Contractor from Sulekha.

Hello, I have contacted Sulekha.com for false ceiling contractors and after I updated my Name and number I received a few messages of false ceiling (POP) contractors who might be associated with Sulekha. Among all of them I like the quotation of a person who sounds genuine and whose charges seems fair. He came to visit my house and as agreed we have fixed the money & time to finish the task. As discussed we need to start the work from monday and it will be finished, in same weekend of (december month). Next day this person called me asking for money to buy the material required for false ceiling and some advance payment for labors. I immediately have transferred him online sum amount of 22k because as agreed he/I has to start work and get it finish in same week but after receiving money later on that day he didnt answered my calls. Next day he sent me a voice message by saying his vehicle got accident and he is seriously injured and asked me to wait for few days to start work as he will take rest for 2-3 days, I said okay and asked him to take rest and start working when he is completely fit. After few days I tried calling him on his whatsapp number which he used to send me false ceiling (POP)images, he didnt receive any of my calls but he used to send me voice messages saying he will resume work in few days and even after that he keeps replying me with only voice msgs by saying that his situation is now improving and he will join soon but refuse to take calls. Next time I called him from different number and to my surprise he picked up, I felt suspicious and about him and asked him return money or start the work. Since then he is avoiding my msgs/calls also and sent me a voice message that he cant come but he will return my money after a month once he has. Now I donot believe this guy and wanted to complaint against him. Kindly suggest.
