Complaint Review: Gold Medal Services

Gold Medal Services is horrible, don't waste your time.  They came out yesterday to diagnose my running toilet. They quoted me $475 to replace the flapper, that's right $475.  The toilet is a 3 year old Kohler.    When I laughed and said I could buy a new toilet for less, the tech called his manager and revised the price to $300. I said see you later and paid a service charge of $30 plus tax. 

My advice is to buy a kit at Home Depot/Lowes, etc. for $7 and do it yourself, or call a local, smaller mom and pop type plumber. I took the route of calling a local plumber who came out today and did the job.  They charged me $149 plus tax. 

How can Gold Medal justify charging 2-3 times more for the exact same job??  The manager will not get on the phone with me to discuss and the rep/scheduler just keeps repeating that they provide 24 hr service and have a limited life time guarantee.
