You can see the opening hours of our services here. You can come to us at any time during this period, you will be sure to wait within a few minutes, and you will not have to wait long for service. It would be best to book an appointment, because then our colleagues are guaranteed to take care of you. In any case, try to schedule it so that it does not arrive 10 minutes before closing, as we will probably only be able to start repairing the unit the next day. If you arrive no later than 1 hour before closing, there is a good chance that you will be able to take the device even before closing so that you can take it even after that. Of course, the repair time can always be accurately determined on site. In all cases, the repair time will depend on the nature of the malfunction and the amount of work involved.
