Hotelopia's dashboard

Good afternon. I write you from Hotelopia, we are an online hotel reservations company. Some time ago I created an account for us but I deleted it later because I didn' t have time for manteining it. Now I want to have an account again for Hotelopia but it is saying me that the username is already taken but it isn' t actually. http://twitter.com/hotelopia: this is deleted and I want to restore the account. Please could you help me?
Thank you very much, looking forward to hearing from you.
