What went wrong...EVERYTHING! From the start of my order to the installation of the flooring. The lack of communication between the store in Mechanicsburg PA and the customer was horrendous. The salesman, who kept stating I've done this for 35 years was a complete incompetent. He just wanted a sale and told you what he thought you wanted to hear. His lack of knowledge of what a third party installer can and couldn't do is what caused me to be dissatisfied. It took 3 weeks from the time of order to the installation, and yet it wasn't complete because the vinyl planking couldn't be done. With all honesty, Home Depot has lost a loyal customer and I WILL NEVER RECOMMEND your store for anything. Lowe's will have my business from now on. I do not recommend Home Depot Home Services for anyone. Customer beware!
