I'm still waiting for my refund

I booked with All Furniture removel to move me from Potchefstroom to Roodepoort and paid them in full. My move was booked for the 15th of Dec. On the 13th of Dec. Robin phoned and informed me that his moving truck was in accident and would not be able to move me on the 15th. In an e-mail he said he will refund me. Till this day I have not recieved my refund. I have phoned him every day to follow up on the progress. For 2 weeks now he is just not picking up my calls or responding to my e- mails or whats ups.
