Unhappy customer

I booked a 3 day vacation through Africastay and was advised two days before departure that our flight times has changed. The problem is flight was now scheduled 13 hours from original time. We were supposed to land in Zanzibar 12:30 pm on the 14 May, instead we only booked in the following day 15 May at 5am. Africastay has not offered to give us the monetary value for the one day that we lost but we were told that there is nothing that they can do from there side. Upon our return our flight was delayed yet again as some documents were not submitted. I requested alternatives such as booking the following week or requesting that the hotel offers a discount. They could not assist with any of these request. I feel that we have been ****** of one full day yet they cant do anything on their side, unacceptable.
