****med by Rates Clearance and refunds in The Hill, Johannesburg

I paid Clint Pienaar R 750 to have my late husband's name removed from my municipal rates and taxes account. This was never done. Mr Pienaar is now not answering my calls or responding to my mails, text and whatsapp messages. I've been to the estate agent's premises in The Hill listed on the invoice I received but he doesn't work there anymore and they don't have his contact details. I've been ****med.
