I called the number on the website and the lady was very rude and told me I called the wrong place when I was looking for an entry level PA position and was very adamant about not giving me the number of I needed to talk to. Anyone know the number?

Production companies will hire PAs, not the studios. Try submitting your resume to the new Mexico film office.

I was there delivering vehicles for a movie/show I personally don't know the number of the person you'd need to speak with on a side note everyone I dealt with was very nice and cordial

Exactly, call the specific production not the studio. For instance, you want to work on Better Call Saul, contact Sony.
