To the OP: am I correct in understanding from your description that you placed a high dollar order with Adorama without either knowing your credit card limit or knowing you were over the limit at the time you placed the order and figured you could sort it out later? If that is correct, then I think you need to reconsider where you are placing blame. If my understanding is not correct, then please clarify.
Try reading what the Op has actually said before Pontificating, The Guy "wire" Transferred the Money, it arrived 24 hours late, Adorama Personnel got "Rule Bound" and effectively told him to take a hike, unless I've read it wrong, and I think I read it right.
Well Natureshot, welcome to the world of Big Business, and the Bigger Egos that work for Big Business (and generally don't much give a hoot about Adorama, as long as the Pay Checks in the Mail), I at least appreciate your frustration and your attempt to warn us of your treatment & frustration with Adorama, situations like this do colour my future decisions on purchases.
As has been suggested in previous Posts, at the end of the Day you control the situation, albeit with some time delay, take your Business else where, hopefully B&H will appreciate you more as a customer, if they do, they get 20k in Business right now & the distinct possibility of another 20k over the next 10 years, we are Photographers, it's almost a Guarantee.
Then, when you get your Lovely new 1Dx, 600f/4 & 70-200f/2.8, sit in the bright sunshine and just, enjoy.
In a day or two you wont give a Flying Frog about Adorama.
