Purefit Keto Charge me after I canceled. Los Angeles, California California

i ordered a free sample where I paid shipping only.  I wrote down a date to inform them if I want more or want to cancel.  I called on that date to cancel.  I asked the girl if I would be charged anything more.  She said, everything is cancelled and nothing else will be billed.  Days later, I received another bill for $198.  I called the same number as before and talked to a girl who said that when I called I cancelled detox.  I said no, detox was never mentioned.  I referred to cancelling everything.  I asked to talk to a manager and they hung up on me.  They are a ripoff company.
