In need of help in Missouri

I have loans with following companies that are all online.

Quick911cash.com
original amount 400.00 - 120.00 to renew every 2 weeks 4 times and then a fee plus $50 to pay down after that
Paid $360 so far

instantcashusa.com
original amount 300.00 - 90.00 to renew every 2 weeks 4 times and then a fee plus $50 to pay down after that
Paid $270 so far

speedycash.com
original amount 400.00
paid $276 so far

cashnetusa.com
original amount 350.00
paid $0

paydayone.com
original amount 500.00
paid $138.50 so far

I just need to find out of these are legal in Missouri and if they are not what I need to do about getting a PIF letter.
Thanks!

CashnetUSA is the only one that I know for a fact is legal. I doubt the other ones are. You can get a coppy of your states laws on the side bar to your right under "US Payday loan laws"

I have sent emails to both Quick911cash.com and Instantcashusa, but have been unable to find a physical address for both. Would anyone happen to have that information. I have had no response from either company and still had the funds taken from my account last week.
