Is mijn betaling goed gegaan?

I had an outstanding invoice for €68,and my number was blocked today,so I paid it in full through revolut. It was processing for awhile and then displayed a message saying something along the lines of "We're not sure if that went well,check your bank balance and if it was taken out regardless of this,if it wasn't pay again." I checked and it the balance was gone,but my KPN has not updated my invoices to paid,what do I do??
