Daphne,
I am very sorry to hear that you are upset with our service, I personally would never use a used alternator belt, but that is at your discretion. As far as part cost and labor cost, I personally did the best I could with the price. Did you happen to ask them what they would charge you for a new alternator with a lifetime warranty? I am pretty sure that would be above 400 alone, but feel free to stop by, or call, because there is not a phone call that I miss.
Thank you you for your time, and again I am sorry you feel the way you do
