Installment LOAN legality?

Thank You for your response. Now when it's illegal, what actions can i take or rights do i have?

Spot Loan - Illegal loan

Blue Trust Loan - They are installment loans. Illegal.

Credit Cube - Illegal lender.

Skytrail Loan Original Amount - Illegal lender.

There are a couple of steps you should take right now.

1. Revoke your ACH authorization
2. Stop making payments if you have already paid the principal amount
3. Send an email to these lenders and inform your decision

Thank you! I revoked ACH and will be closing my account and opening a new one, i still dont trust the loan companies. I have sent them all letters, and have stopped paying on one as i have over paid already (blue trust). I received responses from all the companies except blue trust. Sky trail has agreed to my terms on when i pay just the principle back. Credit cube has not and has been harassing me ever since. Spot loan did not agree either, but i only intend to pay off the principle of the loan. Nothing more.

Update: Credit cube is accusing me of fraudulent activity because I am refusing to pay back the loan and interest. I am not refusing to pay back what I borrowed. I have received numerous phone calls and vicious voicemails. I have sent an email to them stating that I will be reporting there harassment to the AG of Michigan. I just want to know how do I know they are illegal lenders and what should I do? I won't be able to pay back the principle in one payment and that is what they are upset about, however, I'm not refusing to pay it. I just really need some help please!

You are doing absolutely fine, which state are you from?

They are illegal, so what you are liable to pay the principal amount only. If they still disturb you, then make a complaint against then to your states' attorney general.

I live in michigan.

How do you find out what loans are legal and what loans are not?
