Circuit City Credit Card Services- Suck

I signed up for one of those buy this and get no interest for 2 years. Okay so maybe I asked for it, but anyway my first payment was scheduled for like the 23rd of the month so I set it up on yahoo bill pay for the 21st to be paid every month for 2 years. 2 months go by.(cont'd)Just being curious I look at my paper bill and I was charged $35 late fee because they changed my due date to the 17th the second month, then because after the late fee was subtracted from my payment($4.00 short) they charged me another $35 late fee (on the $4.00) the next month. So much for thinking I was coming out ahead on the deal. Maybe they should rename it to Scam City or Ripoff City or Shister Heaven or .... Anyway I'm irate, enraged and just plain angryaboutit.
