tuffy auto service center Cant even do a simple oil change fort wayne, Indiana

Tuffy auto broke my oil fill cap on my 2007 model car and wouldnt replace it. they were the last place to change the oil in my car and we took it back for another routine oil change and they told me it was stripped. I told them they were the last place to touch the car and Tim, the shop manager told me that that doesnt mean that we broke it. I was heated and instead of taking a trip to jail i had to leave. Please people stay away from this place. They are known for doing "shotty" work on cars. They cant even perform a simple oil change. I understand that caps like that can break, but for god sake own up to it and make it right. It is a $5.00 part. Now they lost my business forever and i hope that other people read this and take the advice.
