Very Poor. Very rude customer service, she kept talking over me and aggressively saying she could not help me as well as "did you hear me when I said I can't do this for you?". I paid for a sample in 1/4" material. What I got was 1/8" material. Not what I asked for or paid for. If I had known, I would have never bought the sample. When I asked for a 1/4" sample after being sent the wrong one I was told that was absolutely not possible. Still confused at how you don't have a sample of the product you are selling. Honestly, after the experience I had with customer service, I don't think I will be using the material even though I think it might be a good option for our application. Seriously, I wish I could give a less than 1 star.
