The technician provided a $1,022 estimate for work the homeowner estimated at 15 minutes, then a different contractor completed the same scope plus an additional valve for $260 total. The review notes a $63.92 dispatch fee was applied post-service, and communication with manager Jim involved a callback promise that the customer reported never materialized.
