Geek Squard, do you have to have appointment with you?

I think it depends on the scenario and what exactly they’re fixing. But if you don’t want to make a reservation, you may have a longer wait time.

Yes, you need to call them and they will let you know the slot they have for with date and time they will come out to you . I hope this helps 🐬🐬

Yes it's best to make an appointment so you want have a long wait time.
