A week ago I booked two roundtrip flights through an online travel agency (eDreams), both roundtrips are operated by WizzAir. I've always avoided OTAs, but in this case the tickets were significantly cheaper, so I booked through them. I quickly received emails from the OTA saying the bookings were confirmed, and shortly afterwards I received two invoices (one for each roundtrip) from the airline, including their corresponding confirmation codes.
At the time I didn't see it, but today I noticed that the contact addresses listed in the airline's invoices are completely wrong: they are in different countries to mine (the addresses are correct in the OTA's invoices, so I'm certain this wasn't a mistake on my part). Interestingly, my name is spelled correctly in both bookings. I got in touch with the OTA, and I was told (unsurprisingly) that it was the airline's fault.
I haven't contacted the airline yet, but I'm wondering whether it's worth the hassle given that my name is correct. My main worry is that since one of the flights is from an EU to a non-EU country (I'm an EU citizen) I could get asked for the invoice at the border.
