Liv Care Water Solutions — fraud against amc service

Hi.. Lst year i have taken out contact number for ro service for the company whose ro i am using and with the name of the company i got number of this liv care water solutions, thinking they might be partners i have called them for service. They have charged 10k for 4 yrs of amc and never picks up the call.. They are using the name of big companies like livpure, aquaguard etc as if they works with them and they address only the people who calls for service when i asked that lady that what about my amc, she asked that which company ro we are using and accordingly they give toll free no. Of that company where after calling we get to know that we dnt hv any such amc with them. Today i called an person on whose paytm account i have transferred 10k for amc and now he is telling that he no more works for this ro company.. I am sure he is bluffing.. I asked for any alternative no. Then he asked me to send bill on his whatsapp no. And then after he blocked my no.
We all should together file an complaint against these fraudster.
