I had a problem with my otp code for an headphones delivery as my Amazon account wasn't connected to my email. I couldn't find it via the app so the poor delivery man couldn't leave it with us. He kindly told us he would come again in an hour and for us to contact the customer service. I cannot express how that call made me feel, I handled it so my boyfriend could take care of it, as he is better than me in resolving these situations. Since the start the man was extremely rude to him and then as I was speaking to this man on the phone ( my boyfriend apparently wasn't allowed) I was explaining that the email now connected to my Amazon it was not the previous one that I had access to, so if he could please resend the otp code. He was pushing for me to see in the spam and that he had sent to me this morning at 10:40 am and that it appeared read, which was not true as the only email I had from Amazon was at 12:40 thanking for the verification of the email. When I asked him again to resend it he buffed and almost screamed that he had re-sent it to me. I received it, thanked for the help and he had the audacity to even ask if there was anything else he could help me with. Really really poor customer service, my advise is if you cannot deal and are not happy with a job like this do a favor and look for something else, don't make others life harder when they are in need of help/confused.
