Crazy Customer Service

I got a notice in the mail the other day that my cable bill was a little overdue. So, I went online to pay it and just take care of the whole thing. When I got home that night, I received a phone call thanking me for my payment. That struck me as really odd - don't these CSRs usually call when they want your money, strongarming you into making a payment over the phone? The funny thing is, it felt kind of nice and I wasn't speaking to an outsourced worker from India either.
