I need Appointment to fix my phone, how do i do it?

First step would be to call the store and find out if they do appointments. Otherwise you will need to go to the store and wait your turn. Asking Google won't get it done. Sorry

You have to go there. That is better

All you can do is going and wait I don't think there is appointments that place is always packed

Be prepared to wait an hour and a half when they tell you it'll be 40 mins.

Walk in there. I don't think calling is gonna work, they are way too busy.
