Junk call. Called a few seconds after a call with 'Unknown Name O' called and hung up, probably the same spammers.

Called - stated they were Topix representing AT&T and they wanted permission to refund our account but we needed to give them the account info. I put them on hold a couple of times lasting 2-4 minutes each time. They finally hung up. I called AT&T and there was no refund going to my account.
