Media Markt pick-up ticket?

I just ordered a cell phone from Media Markt that I have to pick up from the market. However, I ordered it as a guest on my laptop, so I don't know where to find the pick-up ticket. Can someone tell me where I can still see it? Or is it enough to show the confirmation email?

You should have received the invoice and / or pick-up slip by email, did you take a look at the attachments? Maybe check the spam folder.

You have received an email with everything in it.

I only received the order confirmation and the item number, price etc. As an email, no pick-up slip
