I have been waiting for my Rates and Taxes Refund ever since I have sold my house at Stretford Ext 1 in 2019. I went to the Municipality, the staff was so rude and even called me names just for not being able to speak their language since I am Zulu and they speak Sotho or SeTswana, I'm not sure. They promised to pay in 3 months time since August 2024 when I did my 1st application as they couldn't refund without my physical presence at their offices. I waited until 2025 January or so. I had already given them my banking details, and accepted that, only to find that they will subsequently ask for the attorneys banking details and have them changed in my presence at their offices. I gave them the attorneys banking details, they promised another 3 months to pay. The lady by the name of Lerato gave me her personal numbers, when I asked for the office number she said they don't use or have office phones which was shocking. She subsequently blocked me and never answered my calls.
