I want to send this email to cash cure...advice please!

I sent my revoke ach letter to cash cure and they replied with the "we are based in Delaware and those are the laws we follow" bulls&$*. But, at the time, I didn't know it was bull crap. So, they set up a payment plan that I had to sign and send them within the hour for it to be valid. I did that. The payments would total alittle over $500 in the end, which would be in January. So, in January, I will have paid over $1200 for a $600 loan.
Now, after seeing these posts and reading other's situations, I have realized this is still illegal. I am a resident of New York and the laws of New York State apply to me and this company if they lend to me.
So, I drafted this letter to send them, but I'm not sure if it is a good idea.
So, could someone, or some people, please read what I've written and give me some tips? And please, be honest! Tell me it sucks and has too many spelling errors to be taken seriously! I don't care. What I care about is getting these scumbags out of my life!!!

So, here is the letter. I have not sent it...please advice if its good or if it sucks! (Thanks):

After doing my research about payday loans, I have learned that even though you are based in a different state, unless you are licensed in my state, which is New York, it is ILLEGAL for you to do a payday loan.
Now, I am NOT one of these slimy people who get a loan and then try to find ways to not pay it. I am, however, one of these people who get a loan, pay it back (and even more than the loan and fees) and will fight to stop having an illegal company take money out of my account!
I have also learned that it is in my right to stop ach debit payments from my account. This is not illegal. What is illegal is your company!!
You feel you can bully people into paying more than what they borrowed. You hope these people are too stupid to research and realize what you are doing is illegal. It is also disgusting and immoral.
You use scare tactics to get people to give you their money after they paid you what they borrowed. I am not stupid. I do not believe you can have me arrested or put my social security number on hold. I DO NOT believe you are a genuine company and I DO NOT believe you help people when they need it. You pray on working class people who are in financial trouble.
