Whitening Fast WhiteFast,bf Unnecessary withdrawal from bank account,Continuing Charges, Scam Internet

I started a certain day trial with this whitening fast company and canceled it 4 days before the trial time is up, I still received the package because it was on the way anyway. I never really wanted it. I did it for a telemarketing internet job that required me to try certain products. By paying up to $7.87 shipping and $1.03 processing charge( AS IT SAY ON THE WEBSITE TOO).
I finally got the product and called customer service canceling any other 3rd party business linking with this company. Customer Service specifically told me: " IF YOU WOULD LIKE TO KEEP THE PRODUCT STILL, WE WILL ONLY CHARGE YOU $10.00 AND THERE WILL BE NO PENDING CHARGES FOR ANYTHING ELSE" I took the offer because I didn't want to go all the way to the Post Office to send the box back.
I let them charged me, without realizing they still had my credit/debit card information on file. So I open 1 of the whitening package and everything was just plastic, I never used it. I kept it in a box. Until recently I checked my back statement and saw a pending charge of $78.41. I called them about it the same night and they are giving me bullsh*t talk about I never finish completely canceling the trial. I told them what they did was NASTY AND EVIL AND THAT I WANTED MY MONEY BACK. They gave me a RMA number and a shipping address to send the package back and that if the package is open or destroyed, a $19.20 fee will be charged on my account. I taped the package anyway and sent it off the next day.
Now Last Night, I checked my bank account statement and I saw another charge of $43.55 from the same "bfwhitefast" A similar incident happen to another customer to me:
