R81000-00 Refund sought for hire and fly on ZS ECK

Echo Skies is advertised on Google as having offices at Grand Central airport. Seemingly they are not at this airport currently. I deposited R81000-00 with an intent to hire and fly a c182 ZS ECK. The Owner did mention that the a/c will be up for sale. To date I have not hired the c182 that I paid for upfront. I would like to have my money refunded and now my cell phone calls are blocked by Marco Duplesis. I find this very frustrating that there is no office one can pitch up at to have a face to face resolve on the matter of my refund. Marco Duplesis please pay back the money and desist from delaying and promising to reply via email. Refund my money and you will not have to block telephone calls.
