Horizon Learning LLC They did not accept a request cancelation I was charged $3,000.00 for 30 minutes of" couching" and sent my information to a collection agency Internet

A few months ago I was contacted by a company called Horizon Learning LLC
I do not know how they got my phone number but they contacted me.

And they offered me to help me make money online at first I reuse to accept but they insisted that they would teach me to make big money online and finally I accepted.
When I told them I accepted .
They made me the following questions
how much money you have in your bank account?
I replied to them that I did not have much money.
Then they asked me about my credit I replied that I had no problems with my credit
then they told me I was qualified to start an online business and earn big money and they would help me to achieve it.

They made me sign a contract and they told me I was ready to go.
A day later I was called by a coach who told me her name, age, etc. ..
But she never told me  what to do to make money online.
The days passed and I started to worry because I had not made ??a single penny.
After a month I call the company to cancel the service but they said they did not accept any request cancellation due to sign a contract.
The problem with me was that because I can not read well in English I did not understand that what I was signing was a loan of $ 3,000.00

Just a few days ago I received a letter from a credit collection company saying that I must pay $3,000.00 on behalf of Horizon Learning LLC.

I complaint is because I have to pay that much money for a service of 30 minutes of blah,blah.

They cheated me because I did not read well in English and also because they did not accept my fo cancelation request.

If anyone can help me because I do not want they damage my credit ..

This complaint I wrote it through the Google translator. Thank you.
