The same happened to me. 10 years ago my personal account was frozen. They requested additional verification. Getting any information on why my account was suddenly frozen lead to nothing. Paypal was not able or willing to explain to me what caused this issue.
This was the moment I decided I did want to do any further business with them.
This was about 15 years ago, and back then this was the first Google result when you searched for "Paypal complaint".
