Costco Damaged my property during installation and refused to refund me

Buyer Beware of Costco special order services! 

What Costco says on their website:

"We Value Our Members

You'll appreciate the quality and value of the products you find at Costco. That's our promise to you. If we fail to deliver on that promise, we'll refund your money. It's that simple."

What really happens:

When we purchased blinds from Costco, and installer did irreparable damage to our home, Costco refused to refund us. Here's what they said:

"Costco only sells product and does not offer or perform installation services for this product. Costco did not "hire" these installers. For installation services you are referred to a local Dealer; this dealer is whom you contracted with for installation and made payment for those services to. This information is clearly indicated on the back of our program brochures as seen in the attachment.

As your claims of damage specifically relate to the installation of the product you will need to discuss this matter further with the dealer. We can request that they contact you directly to do so but will not be able to assist in any discussion beyond that.

If the dealer does not address this matter to your satisfaction, we would recommend you discuss this matter with your Home Owner's Insurance for further guidance."
