Best Provides Installation Materials in Phoenix AZ

I am a landlord that sent this company out to service my rental.  My renters advised me that the guy who went out was not nice to them and had the attitude of why the heck am I here. I chose this company because its a family owned business. They did service the AC as promised, but I will not use them again.
I did call them today to get the receipt and also noted to them that whoever came out to service the AC was not nice to my renters- I was advised that it was the owner- shocked that it was the owner himself that was not nice- as said before, I will not use them again.
