great bottles, keeps water cold for hours with stainless steel also

They did not delivered at door step and asked for self receiving. They did not even informed that the package has arrived. I complained about it then they sent a message. When i went for receiving the workers misbehaved and said that my package has lost. After 1 hour they handed over me the package. Fedex has no services in my area so they used M&P courier for delivery and M&P's workers were very rude.
