Slow Service and Disrespectful communication from the manager

I am very disturbed today, my car has been at the WILLOW PARK branch for almost three months, I collected the car on Friday, and noticed that all the tires are worn out to the thread, and they are all different brands and different sizes, I called them the reception and got assisted by Debby who respectively told me they will investigate. I was dropping the car today because there are things that they had to sort out, I checked the tires with Debby and she promised that she will get the workshop manager to investigate this matter and provide feedback later when I collect the car.

Few minutes after I left the place, I got a very disrespectful call from Pedro telling me to "stop taking chances" even telling me that he can also be nasty. Was I wrong for asking them why my tires are different? Why does he have to talk to me like I am his kid, why can't he just investigate and tell me his finding without being demeaning and disrespectful?
