can a company keep my money when they told me i had 10 days to cancel and when i canceled in 24 hrs they wouldnt give me money back?

I was online looking for insurance when i got a call from a Jonathan Bercowicz and thought it was thru Obama Care, He sold me a PPO insurance that said was medical, Dental, Vision and it covered my Medicine which was why i bought it in the first place. I found out after i bought the policy (what i thought was insurance) from my pharmacist that it wasnt insurance and it didnt cover anything. I called the very next morning to Jonathan bercowicz and ask him if what happen, so we called the pharmacy on 3 way calling and that is when the pharmacisttold us that nothing was covered and that it was a discount card not insurance so Mr.Bercowicz ended the call and i ask to cancel since the medicine was why i bought the insurance in first place. He started trying sell me other things and i told him no and this is when he told me i wasnt able to get my money back and tried telling me he told me this. He lied about everything including the A+ with the BBB (it is a F rating) lost licence also in Sep
