Best Grill Assembly Services in Nashville TN

I’ve used Frog Heating & Air the last couple years and every visit was great with quick resolution. Now they merged with Pioneer Home Services and a brand new HVAC system they installed in December isn’t cooling. I called Wednesday to report the issue, they said someone would come Friday. Someone called Thursday at 4:45 saying they would be there at 5:45 but I had a commitment so couldn’t have them come. I call Friday and my whole service visit was cancelled so they scheduled for Monday. They come Monday morning and spend 30 minutes and say nothing is wrong. Now it’s over 80 degrees in the house and they haven’t returned a call in the last few hours. Maybe I should use another company to fix their work and charge them. Very bad experience not even resolved yet.
