FIrst off, shame on the guy below saying anyone who rates these people poorly are jerks. You may have had a good experience, but that certainly does not mean everyone else does. That's why Yelp is great. Business ratings are an aggregate of everyone's experience, not just yours.
I don't know if I can put into words how frustrating this place was, for me.
I came one day after having made an appointment online on their website. When I arrived after a 35 minute drive, one way, they said they had no record of my appointment and the slabs I wanted to view were buried deep in a stack of slabs. They were able to pull one out for me (which I didn't like the look of) and then said "we'll make an appointment for you at the front desk, and in a few days when you come back, we'll have all of the slabs out for you to view". Okay fine, a little frustrating that their online reservation system doesn't work, but no harm no foul.
I come back on the day of my 2nd appointment, again a 35 minute drive one way, and all of the slabs I was interested in are still buried deep in the stack of slabs. They hand me a list of slab locations in their big warehouse with hundreds of bays that each contain ~10 slabs stacked on one another, and send you off on your own to find them. After searching through their warehouse, if you find the bay that the slab is in, but find its buried under other slabs, you have to walk all the way back to the front desk to ask for them to unbury it. Would be nice if they came with you on your warehouse adventure and could use their walky talky to get a warehouse employee to come help you out, instead of making you walk all the way back to the desk.
Half of the slabs on the list given to me were not in the location shown on the list...who knows where they were. The other half were actually where the list said theyd be. There were ~5 slabs...hooray! Choices, right? Wrong. One was a leathered finish instead of polished...so really 4 choices. Of those 4, 3 were on hold for other customers. So really just one option. I ask for them to unbury the one that was available and it ends up being the same one I saw on my first day there. They didnt have the courtesy during my first appoinment to tell me that the one I viewed is the ONLY one available and there was no point in coming back. They could have saved me an hour of driving.
I called the installer that recommended Cosmos and asked for a different granite supplier. I drove to the different supplier and they had 4 slabs opened up and ready for my viewing upon arrival. I liked one very much and reserved it for my kitchen remodel after about 20 minutes of viewing.
I would highly recommend using a different granite supplier and avoiding Cosmos. Cosmos was unorganized and unhelpful. read more
