Bed bugs in Sura Design hotel!!!!

Bed bugs in Sura Design hotel!!!!

We booked a triple room through Expedia for 9 nights , the first day we found a dirty and not nice room with a dusty and old carpet and I told them, so the hotel offer us to change the room, but we already unpacked our things and just asked them in a kind way to just keep our room clean. Few days later my friend and I started with a little rash in our skin while we were there but we thought it was just a common allergy.
When I came back home the rash was spreading in all my back, so I went to the doctor and according to my dermatologist is due to BED BUGS!!!!!
I ve been in treatment for more than one month now and still are dealing with this problem.
We are very upset with the lack of cleanliness of your beds. How is this possible on a 5-Star rated hotel???. I personally travel every 2 or 3 months to different countries including Istanbul and never had this problem before with any other hotel until now.
I ve been contacting the hotel to let them know my situation and sending pictures of the doctors prescription and they just don t care about it!!!
I ve been calling expedia because I want a or at least a compensation but the hotel refuses to help me with that.
So stay away!!!!
