A1 was once known as Simobil in Slovenia before it was bought (or merged with) by the Austrian A1 company. The centers are now a lot more modern and it's almost as if you walked into a Apple iStore (you can buy Apple products here). Unless there is a new release of a product or something like that there is no waiting, the staff is nice and helpful and mostly knowledgeable (if you're a basic user of phones or even an intermediate one they will be able to help you without a problem). They offer a full spectrum of services from selling to repairing and you can also pay all your outstanding bills. The same goes for the Leclerc A1 Centre which are the main two ones in Maribor.
