Stressful experience at the END

We signed up with them to draw us a ANC, we were swiftly connected online of which it's great, we paid what we were charged and told that we will receive our original contract signed via courier services of which we paid for, within 4 weeks. Our meeting with Leoni was on the 26 March, we had a 10min session everything was explained we agreed and signed. We have been contacting her office, mobile number she gave us via whatsapp and calls with no response, the only time she responded it was via voice note on my whatsapp (after the 4 weeks) that the contract has been signed we still waiting for delivery.... we have been receiving only that message since.... now when we call text or try any form of contact with her, no answer.
