Home Choice Services review: Plumber / shower head

Contracted through American Home Shield. The technician came over to address a shower head that would drip. He took the shower head off and put it back on and said it was due to water accumulating in the shower head. After he left I realized that the shower head was now leaking from that connection, the wall pipe and the shower head. It was not leaking from there before he removed it and put it back on. I can't get any manager or supervisor from the company to return my calls to come out and fix the problem that their plumber created.
