Visiting Angels

We had 4 occasions to use the Carmel, IN Visiting Angels services for my octogenarian father.
The first visit, their office forgot to schedule a caregiver. Fortunately they were able to find a replacement, albeit 2 hours later than originally scheduled. The caregiver did a fine job.
The next two visits went well.
The final visit was the one that really caused me to terminate the relationship. When we returned home, the caregiver had left the gas running on the stove unlit for 3 ½ hours. I had to vent the house for two hours. After two calls to them, their final response, in summary, was that the agreement indemnified them and that’s what I have insurance for.
Could have caused a fire or asphyxiated my father and pets.
I never did receive a call back or anything approaching an apology.
