Hello @farhatdz
Welcome to our Community Forum! Unfortunately we're not able to provide very many details beyond that PayPal was not able to process this transaction due to compliance reasons. You should have received an email with further details. If you did not receive an email with further details, I'd recommend reaching out to our Customer Support by clicking Contact at the bottom of the PayPal website. They're also available through Twitter direct message or Facebook instant message.
My apologies for any inconvenience this may cause,
- Jon K
