Hyundai South Africa - vehicle warranty

In March 2016 I bought a Hyundai i20 1.4 Fluid at Auto Pedigree, I was advised that i will have an extended Warranty on my vehicle. The car has never given me problems, all smooth sailing until December 2018 - while I was driving the car switched off (mechanical breakdown) I tried to turn on the ignition but couldn't do anything, all electrical parts shut down completely and could not do anything to the car. I've called the warranty department and had my car taken at Hyundai Eastrand. A lady named Yolandi called me and told me that the problem is with my engine, and quoted me - I have a warranty and did not follow why she's telling me instead of the warranty department to authorize the claim. I also called Auto Pedigree, they have as well explained that my warranty is active therefore I have no business dealing with them but should deal with the warranty department. I'm frustrated don't know what to do, I keep calling for not to be assisted. I am still paying for my car and its painful to pay for something that is not working.
