Andamansea Guesthouse in Patong

We reached at andaman sea guest House 2 weeks ago at about 3am morning and asked for renting double room for 3 days and 3 nights . The owner was there and she gave us double room for 3 nights . When we opened our room we found one big dead cockroach there and the receptionist was with us also saw that. Okey then next morning the new girl came she calls herself manager and told us we have to leave our room by 12 noon . We said we rented for 3 days where we gonna find another room in short time but she didn't listen nothing at all we requested her too much . She said the woman was drunk who gave us room. And the next day we left room . I've never seen in my life that woman is drunk on duty. And no compensation nothing at all. How can someone ask to leave room at once while we rented room. Really really disgusting!
