Got hit with it as well.
Call - 877-877-1990
BE aware, the CSR ion the call is VERY RUDE and talks quickly. I cancelled but then demanded the first 49.99 charge back, because of the deception on how it was stated in the first place.
Look online under "swingbits.com" and you'll see a BBB complaint. Use that when you call, tell them you are referring this to BBB and see what happens.
Good luck
Bill
