I Would Delete My Negative Review - Black Diamond Is Great
Brett - Grayslake, IL
I posted a negative review of Black Diamond earlier today. While I am disappointed that there was a lot of miscommunication. The company is coming out to rectify the situation. Tony the Supervisor was very agreeable to get the job done and done to the customer's (me) satisfaction. I would definitely recommend Black Diamond to friends and family.
