Madagra Landscaping have not refunded my R56000 deposit

I engaged with Madagra Landscaping specifically with Sascha Vogler in February 2019 to have a garden installed in my new house which was still under construction. The aim was to have the installation done once some of the work was done. So in other words I contracted his services way in advance. He came to quote twice thereafter I paid him R1000 for a handrawn sketch of my new gardens. Should have been a warning, however i proceeded to pay a R56000 deposit with the understanding that he needed to buy the materials the following day which was a Saturday. I received notifications at midnight and at 7 am reminding me that he wouldn't get the specials if I didn't pay immediately. This made me suspicious so my partner contacted him to make sure he would stick to his promise to which he replied that he markets the co on Facebook and all his leads come from there. Thus based on this and his quote which indicated that he was a member of SALI we understood that we were covered and proceeded to pay the deposit . When the work had to start there was one excuse after the next. He indicated he bought the material and would start the following week. None of this happened so we too contacted the supplier who informed us that no material had been ordered in months. We also contacted SALI and they informed us that Madagra resigned as members in 2015. Eventually after many many complaints they offered to rather refund us. After 2 months of promises I posted my complaint on Facebook only to receive a letter from a lawyer challenging me with the high court. I was also sent sarcastic whatsapps questioning my integrity. So Madagra have money to consult lawyers but not to refund one's deposit. To date nothing has been honoured. Very disappointing
