Unpaid Deposit. Disappointed

My sale of Agreement with Balwin properties was canceled in December 2020. The bond assistant sent a cancelation email confirmation that the agreement is canceled. The email also mentioned that Estelle from TC Attorneys will contact me regarding the banking details and my deposit. I received an email from TC Attorneys requesting proof of banking details, if which I provided, I got no response or any communication about my R10 000 deposit that is now sitting in their account. I sent couple of emails, till today I have not been responded to. I called Estelle yesterday, she said she is aware and is going to send me an email shortly, I waited the whole day today. I really don't understand how they do business. Very disappointed... I NEED my money, now more than ever.
