DEFECTIVE TOYOTA COROLLA CROSS AND POOR SERVICE FROM TOYOTA

I bought a brand new Toyota Corolla Cross on 30 January 2024 at Hatfield Bidvest Mccarthy and on friday the 22nd of March I parked at a ba*****t parking in Pretoria for almost 3 hours and when i tried to accelerate the car would not budge. I tried everything I could changed the gear to reverse, park, neutral and whenever I put in drive it went backwards. I called Toyota for roadside assistance since the vehicle is under warranty and they took it to the nearest dealership, which is Arcadia, McCarthy. I requested that they at least provide me with a courtesy car since I have no way to get around and I had a planned trip since the 24th of March was my birthday but I could not be assisted. on Monday, the 25 of March I received an SMS that my car was booked in and given a service advisor but I always have to call to get an update and I was told that yesterday it was taken to a gearbox specialist because it has a gearbox problem, mind you this is a brand new car. we are approaching easter and I cannot travel without a vehicle and i tried to call the head office in Sandton but I'm transferred to Customer Services but no one answers until the line dies. I'm extremely disappointed with Toyota and A BRAND NEW CAR MUST PROVIDE SECURITY and their service is very poor and now I'm suffering whereas it's their fault and I just need a vehicle ASAP.
