BellSouth Screwed Up....

Got in from work today, and what do you think was on my doorstep? A box from BellSouth with a DSL modem in it. Don't know what they were thinking, sending a second one, being I am having no problems with this one.
Anyway, I called them, and they are going to send a UPS return shipping label so I can send it back at no charge. Definitely do not want to be billed for another modem!
