No refunds on deposit for service not delivered

We placed a deposit down for a limo but had to request a refund due to the event being cancelled. We requested the refund 2 weeks in advance, and the only response from the manager was that he would speak to the owner Georgiou, which i never got a response to, i even wasted 1 hour of my time 2 days in a row waiting for the owner to see me but the only response i got was that he was in a meeting and strangely enough there were no other cars there besides mine. After sending an email and calling them - 5 says later - did they say its not according to their policy to refund - there is no paperwork signed agreeing to this - but they said i can get a voucher to the value of this amount!
