Daily care - Fraud done by the company

I was being fooled by this company who is pretending to sell fake health plan along with complementary health products. I received the call from a particular number Nine * Zero Six * Two Seven Six * Two and offered a health plan. I found the plan ok and asked for the details through mail. I went through the details and felt ok with the information. She let me talk to her senior who was speaking so professionally and insisted to take the plan. The money paid through Paytm link provided by these people through the mail. Once the money paid, I received a confirmation mail stating that the welcome kit would receive within *-** days. But now they are not responding. As my current health plan is supposed to be renewed in the month of September. Because of this fraud, I have landed in a big financial problem and mentally tense. I can't afford to bear this loss. I am confirmed that these people are fooling others. I would like to request to take strict action on them so that I can get it to refund and also no other can be a victim of this kind of fraud. They have a registered domain too.
