BOOKING.COM IS A ****

I booked accommodation thruogh booking.con for the 4-6 November at letaba River Studio Apartment. When I arrive at around 20:00 PM the owner came to wellcome me with a very big dog and i expressed my fear for dogs. She went back to lock the dog, to my syrprise when she return she chased me out her property because of my fears for dogs. When contact both the BnB and Booking.com about my refunud they are refusing to refund me even after I explained that I was expelled before I could even check in.
