The hostel hello world marie curie haven't refunded my security money nor they are picking up their phones. Its been a month since i left the hostel but they haven't refunded my security money so i request to look into the matter. I have talked to the warden and she said the money is non refundable as i have left the hostel without telling them a month ago but i have to do that as the rent money was very high and conditions was not good
