I have rented with this company myself and after my dealings with them i would say it is hard to believe any of their staff or their manager would yell. I found them to be quite placid. Maybe a cultural thing? Even i had trouble communicating with them in the beginning but sorted it out with persistence.

I stuck with them because of bad experiences with other seemingly 'polished' and fancy companies.

trust me, try to make sure they understand you point of view.

Oh ofcourse, ignore all of the above in case they have sold out again (in the past 6 months). Cos in that case i wouldn't know the new people.
