Told to "**** off"

After my vehicle had come into some technical issues at the end of July 2017 I had taken it to Mazda Empangeni under warranty. I was told that there was a sensor problem however there was no parts available and the car would only be available on 11 August 2017. The dealership did not even try to arrange a courtesy vehicle for me and told me I must make arrangements with Head office which I did. On the 11th I was then told the part was still not available and no one made an attempt to extend car hire for me and i had to follow up etc. I was then told only on the 21st. The 21st came around and i am niw told only on the 8th of september. I contacted the branch as I dealt with them and after furiously asking difficult questions like who from the branch is following up etc the manager of the branch openly said that the branch will not be held accountable. He further told me i can fone mazda sa and tell them he said to me to **** off and hes not afraid of anyone. I will never consider buying another mazda with the after sales service so poor. And dealerships that treat their customers this way. I hope this manager gets fired because he has no way of dealing with difficult customers.
