Mel, I really appreciate you taking the time to leave this. This one honestly means a lot to me. I did make a mistake on your order, and when you brought it up I was pretty embarrassed. You handled it with a lot of patience and understanding, and that doesn’t go unnoticed.
I’m glad I had the chance to make it right, and I appreciate you giving me that opportunity. The “commendable” part honestly goes right back to you.
Thank you again for the support — it means more than you probably realize.
Great service and support

I received excellent customer service! I got a phone call immediately, in response to me leaving a phone message upon receiving my first order, even though I called a little after normal work hours, and appropriate action was taken immediately. I am very favorably impressed with the service, and also the product quality and very secure packaging.
