I did the same thing at the beginning of January. I didn't receive any confirmation either. So, last week I called to confirm. They said they had received all my info but had to wait two weeks before they could charge my account (two weeks from the Jan 15th due date?). She also said that my first payment may be charged double (Jan payment + Feb payment). So I don't think they send "confirmation." They just begin to bill your account. If you don't notice anything by the first week of Feb, I would call and have them confirm that their records show you down for monthly payments.
