Sears Auto TO SEE OR NOT TO SEE THE CRACK Poughkeepsie, New York

On 5/9 I took my car to Sears Auto in Poughkeepsie, NY around 5PM.  My car was overheating the temp reading was high. the anti freeze was very low.  I informed the Sears advisor and they worked on it till  7:15pm .The store closes at 7pm  I was charged money for the part and labor by 7:30  i was  on the road.  I got a quarter way down the street from Sears the car started to overheat again.  I attempted to contact Sears in hoping that someone would be still there NO ANSWER!  After putting water in the reservoir 3x before getting home.  I found out the next days that the the clamp that Sears put on there was a hugh crack in which no one at Sears told me.  I was very angry and had to borrowed someone else car to get to Sear and get my money back from the misdiagnose.  I also found out that I need a radiator.
