Oil change tire rotate

My last oil change at your dealership did not go well.Your service dept left ALL FOUR LUG NUT LOOSE.Now that may not sound like a big deal to you,you don;t drive my truck,but i do And your service dept left me in a dangerous spot,loose lug nuts pulling my boat down the highway,and your service Manager won't even answer his phone?I do hope the owners of this dealer get to see this comment,I doubt they saw the last one or heard from there service manager about how they can't even get a persons tires tightened.Over the years I have spent in excess of 30.000 dollars at your dealership,I will not spend another dime at your dealership,and the word of mouth that I share with those that ask may not be the type of info you would like having out there about your dealership
