Nothing but a bunch of sells men

Nothing but a bunch of sells men. Tried to Hit with hidden fees 2 days after the job was done. Didn't bother telling me about the bill i would be receiving into on top of the bill we agreed on. Sent photo of finished work to my teenage nephew who doesn't even live there was just over that day.Instead of me the home owner purchaser.I still haven't seen them. Took my old unit without asking and not even offering a core charge on it. Even auto zone gives a $50 core on a $100 starter. They took a 10k piece of equipment. When i asked for it back i was told they would bring it the next working day. It's going on 2 weeks and i haven't seen them yet. Left trash in my yard and driveway. Overall experience was poor.
