arroyo string quartet

I hired Arroyo String (trio) for my wedding. Linda was very nice and helpful, but day of, one of the trio was so off that they stopped playing and restarted a song when the wedding began. I don't know which member was off. I heard it in the dressing room waiting to make my entrance, and I especially heard it/saw it on video afterwards. I also had a few guests make comments to me at the reception because of it. I was disappointed, especially since I paid $500 for what amounted to probably less than 30 minutes worth of music. Perhaps that particular musician had a bad day, but unfortunately, it was on the biggest day of my life.
