When I went in this morning to check my app while on a call with Amazon about an order, I had to answer two security questions to "prove" who I was. Then the same thing repeated itself 5 times! When I called customer service to get an explanation for why this was happening, to say the least, I was highly dissatisfied with the attempts at an explanation. One time the word "normal" even came up in connection with what was happening. One customer service representative said that there were problems in the system for the last 3 or 4 weeks, which I understood could be the source of the problem. On a later call the customer assistant said, upon searching, he could find no information concerning my issue. He could not tell me when it might stop. I got only what seemed to be guesses. With no sense that the matter would be resolved, and fearing that other problems that might occur in the future, would be handled similarly, meaning no real resolution, I called customer service, paid off my balance, and closed my account!
