Angry backlash from asking people if they are licensed and insured
I need my glass patio door (edit) repaired. The whole door is smashed. I have had issues with contractors in the past, so I wanted to get my ducks in a row. I Googled what I should do, and Google gave me 100 pages saying I'm supposed to ask a contractor if they are licensed and insured before hiring them.
There are three main window repairers in my area, and all three are the highest rated through all the rating platforms. The biggest one had AI answering the phone pretending to be a person and never called or texted me back. The second biggest one gave me a reasonable quote for residential window repair, but were very nonpersonable. When I later asked if they were licensed and insured (which I Googled I was supposed to do), they became very angry and said they don't do residential, only commercial, and told me to go somewhere else. This was especially strange because I gathered that they are licensed and insured for commercial projects, they were just pissed for some reason that I asked. The third service which isn't as prominent was very friendly at first, but when I texted them asking them if they were licensed and insured, it caused a major problem. They thought I was someone else and they started sending me angry texts just for asking. The manager called me and smoothed everything over though, but he said he might have to charge me a higher price because he was giving me a sweet deal and I had stirred the pot.
I don't understand why this was such a hassle.
Edit: I'm still hiring the third (which when I wrote in a comment was downvoted so I deleted it, side note i don't understand Reddit downvoting when people are honest). I don't have another option. My window is broken and it's about to start raining. The manager stated they are licensed and insured and the tech will bring the certificate. I just caused a stir by asking. I believe the second one is actually insured too, they just don't want people asking, like "the audacity of someone asking! They should be grateful we answer the phone!" Really weird.
Second edit: I don't believe licensing is required in my state for the type of repair I am requesting. It's known as the "handyman exception" because it's below $1,000.
Third edit: I took the advice here and asked the third service again for proof to be emailed. They sent further angry text messages again. I sent them an angry text and told them I wanted to cancel after I initially sent them money. I'm worried that money is gone. The manager sent me a long text back but I'm too angry and emotional to look it at as he initially gaslighted me. I called a fourth service and asked them if they were insured and if they would send me proof, and they said "Yes we are, but we're not going to send that to you because your project is under $1,000 and we are not required to. We only send that for jobs over $1,000." I believe there are no options that will send me proof, and I am alienating people in the process.
