Car not available

Woodford called me the day before my booking to confirm all details regarding the car I booked, they also messaged via WhatsApp on the day saying if I had any issues to messaged them On that WhatsApp number or call them, however when I got there The car I booked was not available, I ordered an automatic car, they told me they had no automatic cars, they said they had no other cars except a simile manual car, they had given me a discount , i tried calling the number that said if I had any issues but there was no answer ,I the messaged the WhatsApp number but until now I have not received any reply. The agent (Olwethu) at the branch started to get trusted and arrogant with me
