Booking.com complaint: payment

I highly recommend everyone NOT to go threw booking.com I booked a few times had nothing but problems with there website. Meantime my computer was hacked and because of my credit card being issued threw booking.com I lost an aweful amount of money… I went threw hell with my bank it was a nightmare!!!! So now i never give my credit card numbers over my computer. So i booked again a vacation to Florida but when it came to credit card you have to put something. So i typed in numbers to an account that i leave open with just a few dollars in it. Then i call booking,com EXPLAINED my issue !!! paid over the phone with a credit card that had plenty of money to pay for the trip!! Again I explained to Booking.com on how i didnt want my credit card numbers on the computer.. So after that call I open my e-mail conformation and there it is my credir card number over the computer for the world to see WHAT IS WRONG WITH THESE PEOPLE!!!!!!!!!!!!!!!!!!! PLEASE PLEASE PLEASE PLEASE!!! DO NOT!!!!!!! book threw this company I wouldnt be in this mess in the first place if it wasnt for there unsecure website AGAIN I mean this DO NOT book anything threw BOOKING;COM !!!!!!!!!!!!!!!!!!!!
