Strange billing questions from Adobe rep - Really come off as a scam

Adobe has some strange practices when it comes to billing support.

First I had the agent ask me for the first 8 numbers of a card number and the last 4. Leaving only 4 digits missing of course. Then the name on the card, okay that was isn't out of the oridinary. However I've never been asked for more than the last 4 digits by any company.
Leaving 4 out of 16 digits to put together isn't what I'd call secure That combined with the name gives alot of information to try and match up something to lists of stolen card numbers.
A few moments later I was asked for a screenshot of the entire statement which would have contained the entire card number. I of course only sent a screenshot of that one line item. When I called the FCO for the first 8 digits as I obviously don't record his card number. Even he asked me immediately was I sure I was chatting with Adobe it sounded like a scam.

Then 10 or 15 minutes later he asked if the card was issued in the US or Canada even though I was logged into my account and and he stated at the beginning he was bringing up my account details.
And then asked me for the name on the card a third time while she used the first name in the request!

When all is said and done after over an hour and all of the above.
I came away with absolutely nothing more than I started with except having forked over alot of information much of which I found strange, and not all of which I'm comfortable with.
And to wrap it all up when I asked for a request or case number so I could follow up further tomorrow on this request I was instead almost immediately transferred elsewhere.

Next one asked for more informaton and another 20 minutes.... then transferred again to a US based agent who resolved my issue in roughly 10 minutes.

But when all was said and done this took 2 1/2 hours to resolve what should be a simple billing problem.

However in the end I will admit though it was resolved far more more amicably than I expected Adobe would be willing to, but what's fully fair for both parties given all the documentation I had.
Possibly because the guy seen the ridicioulous amount of time and and running around was involved.

So in the end your team resolved my issue to my satisfaction.
However the amount of running around needed to get to someone who could resolve it...
