Conn's Home Plus

They sold me 2800 dollars worth of furniture. I've been paying 125/mo for 2.5 years & still have over 1200 to go. Nowhere in their website can you see what is being applied to the principal. You can't even see past payments further than like the previous 8 or so. I did my own research & found only through looking at my own credit report that they officially are charging me over 5200 for the loan of 2800. Wtf? That is 182% of the original loan value! How is this legal? Oh yeah, that's right, I signed their miles-long pages of documents. Be warned: this place lives up to its name, "conns".
