Castle Payday Unbelievable Scam Watersmeet, Michigan

Unfortunately I was stricken with Multiple Sclerosis and have been disabled since 2011.  With all of my medical bills and the smal amount I receive monthly from Social Security.  I am having to live on less than 1/3 of the money I was bringing home when I was working.

In need of a loan, I mistakenly replied to the loan doument they sent to me.  I borrowed $800 and was told I would havee to pay back $1360.  Seemed like a deal I could live with.  

 Unfortunately now that the first payment is due. they want me to give them $560 of the total loan amount payment they say I would owe them of $8560 because the finance charge is 777.6530% (?). My mind is blown.
