BTW, when I called them for a credit increase, they 'commented' that I had made a rather large purchase on the Visa at the competition.
That would annoy the hell out of me. If you managed to bite your tongue, you're a better person than I. I'd have been asking if they have a problem with that/making some facetious comment about it not being my problem if my local Macy's can't stock the items I want to buy/asking if the CSR would be so kind as to provide me with a list of approved establishments for use of my Visa.
Then I'd probably regret it. Me and my big mouth.
