REMAX TABLEVIEW ESTELLE MAY

I have received an Invoice from REMAX TABLEVIEW Cape Town, Agent ESTELLE MAY to pay rent for August 2026. I gave my notice at the end of May 2026, paid for June and July (2 months' notice) rent. I am told I am liable for ANY rent due, as she has not found a suitable tenant. HOW IS THIS LEGAL? Which means she can sit on her buttom, doesn't need to find a tenant cos she is charging me for the rent. This is disgusting, day light *******, a SIN and absolute BS. She doesn't respond to my emails, has not refunded us our deposit but is comfortable to send me RENT DUE BY YOU invoices. SHOCKING ... Something needs to be done about this urgently, I am sure this is NOT RIGHT at all.
