AT&T Cingular partners SMS SCAMS Internet

I called today and Marta, an ATT rep (rep# in my recorder) told me that ATT was refunding me my $49.95 on SMS scams because "their system knows it was a scam", either by knowing I never contacted that company, never downloaded a thing, never replied one of their SMS (and who knows how many other records from thousands of clients, and indicators they have to verify I never actually engaged in those products), etc.

We know a company NEVER refunds any money at least that money is in their pocket, because if there's 1% of chances of them not recovering that money from "the culprit third party", they'd lose that money. UNACEPTABLE! 
So we know it's not "third party's" fault. Let alone ATT gets a share of those charges (Google it and you'll find 30% and 50%).

Any company using ATT as a "payment method" must have a relationship with them. It's not like "They are trapped in the evil system scammers made". Scammers need to partner ATT to get their system working with ATT, and those scammers have no lobbyists setting up the wireless industry rules.

So, I asked, "If you have that info why ATT is not stopping those scammers? You are refunding my money but not flagging that company.

She replied that "ATT doesn't have the human resources to review every customer's account".

REALLY?

Is my bill written by hand by a human been along with the other millions?
There are systems for that, and yours ALREADY tells you I didn't engaged in those products.

The number I received the scam SMSs is reported by others in internet, which means THEY KEEP SCAMMING and ATT didn't do a thing.
