Rude manager

If you have a guy by the name of Ahmed with the cell number zero seven two Five seven eight seven eight six nine that works in your division. This man is very rude and should not be dealing with potential customers. I simply asked him if one of his cars is a 2019 an he says I should speak to someone else in which he gave the number for the other person but my point being is that his name is on the cars.co.za ad so I ask him, so you telling me you don't know if it is a 2019 model. The man calls me on whatsapp in a shouting tone asking me who is buying the car. So I said thank you sir an dropped the call.. I am trying to help my father in law buy a new car because he does not know how to use online platforms and does not always have enough airtime to make alot of calls........I am mearly giving a review of the behaviour of this man and he is now calling my in laws threating to su me for laying a complaint. You decide for your self if you want to do business with people like this.
