Cancelled by Establishment but safarinow wants to pay back 59% deposit

Last night I made a booking through safari.com and paid deposit and about 5 minutes later I get a message from tge establishment saying that they can not accommodate me I must cancel where as they showed accommodation is available and made me pay. Now whe I look at the terms and conditions of the cancellation safari says I will only get 50% of my deposit back but I am not the one who wants to cancel its tge establishment that sent me a message to cancel. Now I have been calling safarinow and their phones are not going through because I believe I should get my full refund back as this is not my fault but I am not getting any assistance not through emails or calls from safarinow. This is day light *******.
