2012 Watch it out if you buy and install flooring material thru HomeDepot !!! Flagstaff AZ

We ordered laminate floor materials and installation services from home depot, it cost us about $6500 in total for about 1060 SQ areas. However it took them more than 5 weeks to delivery the material instead of two weeks when I was told by store sales, during that time I have to call them several times to get an update (the sales told me to call 1800 number, then 1800 number agent told me to call store!) , the unexpected delay of delivering material cause may issue of my other upgrade projects. Then there is installation, my house is located in Flagstaff AZ, so the installation services are handled by Western Flooring, when two guys showed up, they told me they need to resurface the floor which is about $550, they want to rebuilt six of my fourteen stairs because it was not even!, and will be $600 (one hundred each), I told them NO, they came back told me there is good news after they talk to their manager, it will be only $300 to rebuilt six stairs, I decided to only let them to resurface the floor, and I will do the stairs myself, if I know that ahead, I will install the entire floor myself knowing the hardest part is the stair installation. Another note, after they resurface and install the floor, one of my door can't not open all the way anymore! They overdone the resurface and I have to hire someone to trim the door bottom! So watch it out if you want them to install yours!
