Cali Bamboo Lowes Hardware I have a problem with the bamboo flooring scratching very easily San Diego California

The problem with the floor isn't due to expansion its from shrinkage, therefore epansion gaps in no way play a factor. If the problem was from lack of expansion spacing then the flooring would have buckeled.  I did extensive reasearch and nothing showed the T molding where they said it should be and if the molding were there the gap would have bee too wide for it to cover the space as well.

I have installed T&G hardwood flooring that I have never had an issue with and its more difficult than snap together floooring.  As far as the scratching,  I have had T&G Oak flooring with a poly finish in my current house for ten years and I had it in my previous house for 18 years (The new buyers commented that they were glad that they didn't need to have them refinished before moving in) and the the current house is still in great shape.

Glue down bamboo can under some circumstances be refinished, but floating bamboo can only be recoated which will not hide the scratches. That information is from the National Wood Flooring Association. 

At no time was installation a factor.
They seem to disagree with you. I am going to go out on a limb here and say that the installation was done by you. As if the installation was done by an Independent Contractor you would be going after them and mentioning that they forgot to put in the appropriate moulding.

The problem is that if you relied on what some employee at a store stated for installing the flooring, you really had no business doing the install. As it sounds like you failed to leave an appropriate expnsion gap, which in turn as the  wood expanded caused the floor to separate. It is possible that an inappropriate installtion can void a warranty regardless of the issue.

The scratches may fall under the same type of lack of knowlege. No type of hardwood or bamboo floring is scratch proof, for you to get several scratches does make one wonder what exactly you were using on the floors. Also, contrary to your statement Bamboo flooring can be refinished.
