Minor's Auto

Brought my *** in for a heating issueTwo days after the radiator drain plug falls out on the highway and my vehicle overheats and stallsI bring it back and they state that I have a bad head gasket which shot out the drain plugOnly after do I find out this is a highly unlikely excuse for neglecting to put the plug in properly and causing the blown head gasketNo head gasket problems existed before this event, my engine died months later
