Velile Tinto Cape Conveyancing Attorneys refusing to pay my money

Worst experience I received from these people. First time seller and my agent used this firm to assist with registration. In January 2023 they said they pulled a schedule for my rates from the City and that schedule had me owing 18k to the City for rates, we agreed they would bridge the amount so registration can take place. Unfortunately the sale of the house took very long due to issues with the plan. The process then continued in Nov 2023, now Dec 6 2023 their conveyancing secretary who was dealing with my case paid an amount R49603.73 of which 12 932.86 was my rates and 36 670.87 was for an account I was not aware of. When I enquired what the 36 670.87 was for I was told to ask the City, ok so I called the City and it turned out that it was a billing error and it was corrected. The City agreed they would pay the money to the lawyers after registration. Now when they bridge an account they charge interest and I have been questioning this thing because I did not authorize the bridging for that account and no one has answered me. Finally came the day of payment they just paid money into my account no communication as to how much will be paid and no statement of account. To my surprise they have deducted the amount with interest when the error was made by them paying an account they don't know and did not confirm with me either. I went to their offices immediately and I was attended by one of their senior associates and I told her what happened and she was not aware of this so this means the conveyancing secretary did not share this error that she made with her seniors. The response from their senior associate when I told her the issue and that I want my money and I am not going to wait for the City to pay them and then they can pay me. She said she will investigate and if all is as I am saying I did not confirm this amount then they will have to pay me and then they can chase the City of Cape town for the refund but she will ask guidance from the Directors. I sent her all email communication telling their secretary I was not aware of that account and I'm not happy that she made a payment without confirming with me. Instead of telling me what they have decide from her investigation this woman sends an email to the City of Cape Town and she CC's me asking for a refund of this money, when I told her specifically that the error that their secretary made must not affect me and she agreed. They have been quiet since the 16th of February I even CC'd their CEO in my email and he has never contacted me to find out what happened. I am being undermined because I'm a black woman selling her house in the township they think I must keep quiet and accept whatever they did with my money. I will not keep quiet until they do right and pay my money and then they can deal with their secretary and the City of Cape Town.
