Chas Everitt staff refuses to refund me!

A house was advertised by agent Bradley Edwin in 2023 in Shallcross, Queensburgh. I viewed the property with the owner and your agent. The agreement was that the owner would take monthly instalments from me to purchase the property but I needed to fix the pool. Bradley then stated he fixes pools and does pool maintenance. I paid Bradley into his bank account of which I still have proof of. The owner then decided he wanted extra of the monthly instalments towards the sale of the house to which I declined. I did not purchase the property but Bradley was paid R6970.00 for the pool repairs. When I contacted Bradley he said he would pay back the funds however gave excuses upon excuses. To date, I have not received my refund from Bradley. He ignores my messages and refuses to take my calls. It is now almost 3 years and nothing. Is Chas Everitt aware of what your staff does apart from marketing properties for you? This is your representative that refuses to refund me. We are all trying to feed our families, let's do it with some honesty atleast. Even if he made monthly payments as he initially said he would do I would not have had a problem. But it has been 3 years now. I cannot wait anymore. Unfortunately this is what it takes for me to get a reply and hopefully my money back!
