Auto repair service near Hope, AR

Took 2010 car in for oil change before business trip. Got less than 150 miles & filter o-ring blew off, stranded on side of road for 2-1/2 hrs, missed opening event for conference, had car towed in & had to find another ride to conference - same on way home, had to have someone meet me to drive my car back to where I needed to drop off the borrowed car. On Sept. 28 I hand delivered letter manager took letter, said he would forward to owner) explaining what happened & asking for refund of original oil change plus expenses of over $300 incurred for towing, repair & new oil filter & change, etc. It has been over 30 days & they have not responded. I'm a 58 yr old female who always has car serviced before trips so as to not have mechanical problems & be stranded on side of road. BOO to you THE OIL CHANGER in Texarkana.
