Why PS does not buy by PayPal?

I wanted to buy now for ps4 the plus abbo.

The payment method is PayPal.

But if I want to complete the purchase comes constantly the error message order could not be processed.

The PayPal account is correct.

Bank details would be confirmed and direct debit mandate given

Can someone help?

Meanwhile, paypal has such a policy that you should deposit a 2nd account or a 2nd credit card

ka how long that works or if that remains, many think the papypal so under 18 years to filter out
