Jiffy Lube Jiffy Lube's Mechanic failed to tighten the oil plug in my vehicle Nationwide

 I have been using Jiffy Lube for many years with a few problems from their mechanics. This time was the worst. Not only after waiting well over 1 hour for service. the mechanic failed to tighten the oil plug again. The plug fell out while driving on the highway while towing a boat behind me. The engine shut off and I was almost killed while trying to get accross traffic into the break down lane. I had to have both my truck and the boat towed. Now they won't even answer the phone to resolve the repaire shops billl. It was 100% their neglect to do this service properly. It was amazing that my engine did not blow up.
