BellaBrite HydraWhite Debited my account $136.11 and $158.39 AFTER cancelling both. Internet

I initially ordered trial products from Bellabrite and Hydrawhite (same internet site). After receiving the trial products, I realized I couldn't use them because of receding gums. I called and cancelled immediately. Since then I have had to call again to cancel. My account has been debited from both companies 3 times now without authorization. One total is $136.11 (Bella..) and one is $158.39 (Hydra...). I accepted the cost of the trial $1.95 each, but this is now beyond reason. I have the email cancellation confirmation, yet my account is still being debited. When I spoke to the rep today, he said it showed my account wasn't being debited and it was "past time" to receive any credits back to my account!
