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.
HARRIS - Grayslake, IL
I am hugely disappointed in Black Diamond. I requested the install of 3 fans for our bedrooms. Doug, a very respectful service man gave me an estimate. A week later Doug and an apprentice showed to do the installs. After the fans were installed Doug showed me that they were working. I should have asked Doug to show me step by step how the fans and lights were working. What I came to find out later that night was that I could not work the lights and fans independently. When I called to complain about this Black Diamond sent out another electrician. He told me I was originally quoted on just bringing electric to the fan so the fan works. I did not request that the lights work separately from the fans. How am I to know that I had to ask for this? I am not an electrician. I bought fans with lights and remotes. They couldn't even install 2 out of 3 fans with remotes. I am now being told I have to pay another $420 on top of the $1450 I already paid - because I did not ask for the functionality. I only asked them to install the fans. I called on Saturday after the second service man left giving me the $420 additional quote. I left a message asking for the owner Rick to call me. I was told Tony the Supervisor would call me that day. It is two days later and I have heard nothing. I'm furious.
Response from Black Diamond:
We're sorry for the frustrating experience but glad that we could get this resolved for you - thank you for giving us a chance to make things right and leaving us a great review on the 7th.
