Pretty standard behavior for big companies. Airlines and telcos are the utter worst... you have agent A on the phone on Monday, who promises X to be done by Wednesday. Thursday, you call again, get agent B, who says he doesn't see anything, not even a call log, from you, but of course he apologizes and it will be done by Friday. (Experienced customers of telcos will know that the drama will unfold that way for months... until you're fed up and involve lawyers)
