Security issue

I have a serious issue to deal with concerning the AT&T Uverse account at the office of Dr. *****. As his network admin, it is my job to find a solution; however, after hours and hours on the phone with level two tech from AT&T, techs from a company called Security Metrics, a CC processing company called TransNational and techs from the manufacturer of our newly purchased and installed second router at NetGear, no one has a definitive answer. It all boils down to one lousy open port on the AT&T router that they have open by default for their own use.

In order to be PCI compliant with our new CC pocessing machine which reads the newer CCs and even takes phone pay services, there can be no open ports on the router. AT&T refused to help. Said they could not close or filter the port, it was simply "too bad". 

I desparately want to talk to whoever the second level district manager is for the Burbank area. I'm at the office Tues, Wed. and Friday from 11 a.m to 6 p.m. the phone number is *****. If no one contacts me, we have the choice of pulling all our business, internet, cells phone, land lines, etc. out of AT&T and find an ISP who understands the importance of following government required regurlations. With a company as large as AT&T, it seems like someone would have dealt with this problem already. The company, Security Metrics, that does the scans, has told me they have hundreds of customers that have the same issues with AT&T Uverse.

Someone there needs to address this issue, NOW!! It will only get worse with the new Visa PCI DSS requirements.
