Deleting my account

Hello,

Please help me.

I have listed my property at a very low rate without really knowing what the booking.com commission charge rate is and then I realised that the rate that I would be getting from the reservations, is ridiculously low. 

I have tried increasing the rate but still the website is still showing my ridiculously low rates and I am receiving bookings which I do not want to accept.

Would you kindly let me know how to change the rates as soon as possible so that they will become effective with immediate effect or would you please let me know how to delete my account from booking.com as soon as possible as I do not wish to have guests living in my property for such a low rate.

Please reply asap.

Thanks

Caroline
