Don't really know why it was put in at 24%. They insist I must have clicked on the wrong thing/ not chosen the promotion, etc.
And its too late to change it. Only one person I talked to at the bank acknowleged that no sane person would willingly accept that rate over a 0% offer - so there are some human beings at BoA - very few though, the rest are idiots and criminals (in my view

).
That first month I checked my account online, the payment amount stated included about 1/2 month's worth of intersted because of when the transaction was completed. The following month's interest was alot more, so the payment went up. Of course, since I thought I was paying 0%, I assumed the payment amount was correct.
Since I had already set billpay up for $500, it didn't cover the required minimum of $722. So I was late.
There is some good news though - I got a buyer for my old house. That will allow me to close that BoA mortgage. So that will take about $4000 a year in interst from them, plus the $5000 or so they will loose in debit card fees from my business account each year. Plus of course the accumulated balances in my accounts.
So what I've learned - ALWAYS read your paper statements, baby.
