Query: Terrible customer service

This product arrived late, despite guaranteed delivery saying it would be at my house on time all day, until it suddenly wasn't there. When I called Amazon to fix it, they blamed the delivery service - which is Amazon's internal delivery service. Their response was basically "well, it's not going to get there, you should just wait a couple more days." I needed the product that evening for a gift, and all the other places I could buy this product were closed. I had to cancel my order and go to a salon across town the following morning, and was lucky that they were able to help me - but Amazon really dropped the ball on this one. Product itself (purchased from a salon) is good, though I'm not sure it's really necessary for the brazilian blowout. Honestly, I think any sulfate-free shampoo will do. Another shampoo that I use had better results with the brazilian blowout than this did.
