Murphys Transmission and Complete Auto Repair

First of all, if I could give Murphy's 0 stars I would.  Until 2018, I had received pretty good service from Murphy's.  Had spent thousands of $ for car repairs on 2 older cars.  On  my '99 Durango, I had recently developed a coolant leak.  Was using about 2 qts of coolant every 60 miles.  Was getting a sweet anti freeze smell inside the car and noticed some coolant on the garage floor.  Went back to them because they had previously replaced both hoses and the radiator.  Figured that if they failed I might be covered by "warranty" or "good will".
     Needless to say, Chris called me and told me that the lower hose was leaking.  They had replaced it, the first time, on 06-15-17.  Second time failed on the Dan Ryan Expy in 90 heat.  2nd time was 06-23-17 with 92413 miles.  Had to have it towed to Murphy's.  Now, on 02-21-19, with 101762 miles, Chris told me that it was leaking because it had rubbed against the frame of the vehicle and a hole had worn thru.  I asked him if the hose had moved and he said no.
     He said the repair would cost $189.46 parts and labor.  He couldn't do anything about the price because  it was "out of warranty".  I told him the mechanic should have noticed that the hose was making contact with the frame or very close to it.  He didn't say anything.  He said they replaced the old Dayco brand hose with Gates brand that was bent better.  I contend that I should NOT HAVE PAID ANYTHING for the repair because A. They were not conscientious when they replaced the hose the 2nd time and should have seen the frame contact or close to frame, and B. Warranty or not, hoses do not fail in 9349 miles.
     If I had known how this was going to turn out, I wold have never gone back to Murphy's.  Thus I will never darken their doors again and recommend that nobody else does either.  I asked a friend who is a mechanic/repair shop owner in Orland Park about this and I will not say what he said about Murphuy's.  Orland Park is too far to go to from western burbs.
     Originally I offered Chris to maybe go 50/50 on this but he refused to budge.  I am so aggravated about this and mistreatment of a long time customer I am now seeking 100% reimbursement of the $179.46 I paid.
