I had a delivery problem. I shoveled a path to my porch door and they threw the 2 blue envelopes on top of the snowdrift instead of inside the porch door. I don't know if customer service is in the US, they say they are but I doubt it. Immediately they start asking for my info to confirm who I am. It was non stop thank you very much and thank you for being a Prime member. They kept repeating everything all through the call. After about 10 minutes they had to transfer me to someone else to help me. After about 15 minutes of this condescending crap they promised to fix the problem and give me a credit on my next checkout. Well there was never any credit given and today I had a large package wedged up against the porch door so I couldn't even open it. I had to go out another door and walk back on black ice to get the package. I wonder if it's even worthwhile to call them again.
