I have received a reply that I need to send my id and a utility bill in order to unblock my account. I will do that.

But I would like to point out that there hasn't been any warning or anything about the need to verify your account if you are withdrawing with paypal. I followed the guide published by YOU here:

https://wirexapp.com/blog/how-to-buy-bitcoins-with-paypal/

To me it seems like your are fishing for people who open accounts in a fake name or for people who don't want to send an ID. You want the people to withdraw the money and then you lock their accounts and ask for documents. You can say it is due to your bank but then there should be a big red warning in your guide which is among first results when googling "How to buy bitcoins with paypal".

I don't see a step in your guide that says "Send documents to verify account." To make it even more obvious you say this in the guide:

"What’s Next?
Congratulations, you have bought bitcoin via PayPal.

Next, we suggest you start verifying your account. Verified accounts have better benefits, such as more funding options and higher limits. "

Which clearly implies you bought bitcoins with paypal BEFORE verifying the account. Clear deception and I don't think you will even reply to this post because what you are doing here is pretty clear.
