Booking.com complaint: False Advertisement on hotel reservation stated Free Cancellation – No prepayment needed

I was on Booking.com website and made a reservation for the Comfort Inn Suites Miami Hotel. The website stated Free Cancellation – No prepayment needed it said You can cancel later so lock in this great price today. After I made the reservation and provided my credit card. My ation sheet said it was a non-refundable charge. THIS IS FALSE ADVERTISEMENT!! I would have never made reservations for Aug. 6th if I knew it was non-refundable. I talked to several people at Booking.com who refused to cancel my reservation Aya B., Amira M., Elene K. Hycinth and they were all very rude and refused to cancel my reservation. I sent 5 emails request this reservation be cancelled and a full refund to my credit card and they refuse the refund. I will be disputing these charges and I will never do business again with Booking.com. THIS IS A VERY UNETHICAL COMPANY.
