worst experience ever

it was the worst experience ever i booked a room for five days in Milan Italy in a hostel called "family hostel Milano " after one second of my booking i discovered that the room that i booked was not mixed " and as I am a man i cant stay. I called the hotel directly after 4 min or less they told me we can't do anything you have to call booking, I kept calling booking for two days all the customer service were not series and they didn't help me and I had to tell the story from the beginning to every agent differently, they didn't help me and they didn't even return me back my money (70 euros ) or even gave me a voucher or alternative solution,i asked at least for changing the dates they didn't , they are just ******* when u pay for them you are not important anymore they just kept telling we will contact the hostel and then disappeared, the worst customer service and worst service ever i really advise you not to book with them because they just care about taking their money
