Frustrated

I booked accomodation for the 22/01/2016 to 25/01/2016 with Heidi whom I think is responsible for bookings then decided to change the dateto 23/01/2016 to 26/01/2016 for 3 nights , accomodation fees are paid in full , we are now in Durban from Johannesburg and being vacated from the premises by Danie the manager as he say his records show that we were suppose to leace today and Heidi is on leave and he refuses to contact her , we are now stranded with nowhere to go
