Quality Tune UP Shop / Arden Way

I brought my 2005 Durango in on 7/ 11 2014. my car was overheating they change the thermostat proximately 2 hours maybe 3 at the most car ran for a month and then it started overheating again. so I brought it back because on the back of the reciept it says you have three thousand miles 3 months. The young lady is not a mechanic said she smells like coolant was leaking when I arrived. My car was not leaking any fluids from the radiator or anywhere else when I got there but they diagnostics claimed I need a new water hose and a water pump and informed this is not related to the original problem and it's not covered under warranty this was an existing problem that because I spent $448 I still have the same problem I have dropped it off at a new shop because I no longer trust them. They gave me a bunch of what ifs but apparently the original problem with never fixed it which resulted in a leaking hose in a league in water pump.
