So, a mechanic did some work on my Dodge rear diff.
After that, a speed sensor on the rear diff failed on the same day.
They are now telling me that it is a purely random coincidence that it failed on the sale day as they did work there. Asking me $156 to fix it (it is a $30 part and a 5 minute job).
They do not agree to just fix it for me for free. So, I would like to know if there is anything I can do to make their life a little more difficult, such as bringing some complaint somewhere that they would have to answer to etc.
I could sue in small claims court, and probably will win, but that means taking time off work.
