Remax wont Refund

SO I moved into a property in 2012 owned by a Mr Van Den Berg (I believe he is the owner of remax I stand under correction)At the time the property managers were Prime property portfolio who I paid my deposit to a total of R7095, the owner since changed the property managers to Remax (who I believe were the previous property managers just a new name), Now its time for me to move out and guess what, Remax denies any responsibility and in addition refuse to give me any contact details of the owner, I find this ironic as now that its time to pay back my money I have endless problems, I have been dealing with Yolandi who I believe is in the finance department. Who requested me to send proof of payment which I did and when that was sent now theres a problem again. SO Mr van der Berg I will simply hand the matter to my lawyer since this has to be handled legally?
