Paypal — Account limitations without any reason

I am a course-hero educator. According to the course-hero policies, I have to withdraw my earned money using PayPal. This is the first time I am using PayPal to withdraw my earned money. At the withdrawal, they mailed me to provide information. I just follow their instructions to provide them with the pieces of information. In this process, they limit my account permanently. I tried to contact them and mailed so many times. They were rude and did not respond properly. They were saying that they have the right to limit any account. They should have that if someone is doing unethical work. I did not do anything wrong, so they should explain to me why they did limit my account. Also, they should return my right to transaction as soon as possible. It is my own money that I earned by myself, they have no right to hold the money. Kindly accept my petition and help me. It is urgent.
