Booking com Holoday inn system error

I made a booking at Holiday express Amsterdam immediately after I realized it was an error I was charged 360 euro to me this is very unfair as the booking is 5 weeks from the date

I think booking .com must check there system as I will report this as ***** You can call me as per my details at booking .com or email ********** Holiday inn said the booking was cancelled After 24 hrs this is not true as the booking were cancelled within 15 min

Await your response
