Mavis Discount Tire review: refused to correct their work

Shirley, new york location replaced saturn relay power steering pump at a cost of $442. It is leaking and they tell me they don't have the equipment to see where the leak is - how about a flashlight? I used to go to that same location on a regular basis but the new management is rude and evasive.
"first, your power steering pump itself may leak. The leak would be at the point where the pump shaft exits the pump body and is connected to the pulley... If you have a soft hose leaking it's best to replace that hose. The last and most common power steering fluid leak location is in the actual steering gear or rack." - info from the internet.
