Coming off a horrible-feeling experience with wrench.com where they intentionally skewed my call for their mobile mechanic to come check out a couple of problems my car had after their repair. They want to treat it like a non-related service call and charge their high diagnostic fee.

I really can't prove anything. Yet, I know, from a customer expectations and customer retention and customer positive word of mouth they have really messed up. I'm dedicating myself to getting my disgust with them to several review sites like yelp, car talk, & consumer affairs. Then I'm going to find out who the CEO is of one of the venture capitalist backers and tell then where I shared my experience and suggest that whatever business model wrench sold them on probably is lacking deep understanding of how to build a positive customer experience.
Whew! Thanks for letting me vent.
