Failure to refund deposit for canceled booking

I cancelled a booking for one night at Emerald Resort & Casino in February. I've been going up and down trying to call them and emailing numerous times. I sent through my Refund form to Nthabiseng Mabote and she was of no help. We are now approaching the end of March 2018 and i'm still waiting for a refund. I received a call from Ellen, who acted like she was trying to assist but she also failed. I'm still waiting for my refund. I've worked hard for my money and I want it back.
