Recently i got about 3 girls I'm trying to setup dates with but I'm having a problem trying to call them.Like i don't understand.

Its been at least 1 week for 2 of the females and the other one is about to be 4 days.

I know your suppose to wait a few days and i have but how do i continue setting up a date (by calling) if she doesn't pick up the phone?

I was thinking texting her " hey" and then when she replies call her on FaceTime.

For me i assume everyone's busy and i don't expect them to pick up.

And it's a red flag (from what i heard) to setup dates through text?

And also when i call her/all of them i'm gonna talk to them for a bit to build comfort.

Btw I'm 17 in high school.
