1999 Honda Accord Coolant Leak

We recently had the timing belt/water pump replaced on the car. Returned home, pulled in garage, noticed small puddle of coolant under car (center front, directly behind radiator). Wiped it up, contacted dealer and returned car for inspection. They took it in, said they didn't cleanup after repair properly, and said it was now OK. Returned home, pulled in garage, looked under car, small puddle of coolant under car (same spot). Radiator is full, overflow empty when cools down. Don't see any hose leaks best I can tell. Not sure if they don't know how to cleanup or if new water pump is leaking, etc. Thanks
