You fell for that, so the company will not give you a refund, nor should they.

However, since you used your debit card, call the bank and tell them that you were charged the wrong price.

i doubt that you will get a refund
but if you do decide to send the stuff back, please put a tracking label on the package to be sure that someone actually got it.
You dont want to be out of the product and the money too.
Call the better business Bureau and see if anyone else has any complaints on them.
I honestly dont see how they got you to buy something that you did not want soo I couldnt really see any criminal charges as a result of same
If that should happen again, just hang up the phone or walk away
it is YOUR money and YOU decide how you spend it.
