Hello, @rahimhamada. To submit a request to have your PayPal account downgraded to a Personal account, please log on to your account, click Contact at the bottom of any page, and then select the topic that best fits your concern to see options to communicate securely with Customer Service. If a phone call is not immediately available, you may be able to send a message.
Alternately, you may send a Facebook Private Message (https://www.facebook.com/paypal) or you may send a Twitter DM to @AskPayPal to receive assistance via a non-secure channel.
I hope this is helpful. Thanks for your patience during this time.
