A few days ago I payed for my iPad order with PayPal but they did not receive my money

A few days ago I ordered some products. On the website from the firm I payed the products.

the name from the firm is Oriveda. On my iPad I could choose to pay with PayPal or ideal or with a credit card. I clicked on PayPal and payed my order.

on my bankaccount I saw that I payed to PPRO Financial Ltd.

I send a mail to the firm but they did not receive my money. I chequed again their website and they told me that their website had no problems. It was my iPad. How come? I thought that Apple has a good security.
