@pedros10 is right. Responses can get light over the weekend but they will trickle in by Sunday night and then a bunch more at the beginning of the week.
If the person absolutely doesn’t want to communicate with you, any spell of yours could backfire with unintended consequences. 
With that warning out of the way, many on here have had some success with the Honey Touch. 
I personally would swap out the red candle for a yellow candle to represent overall communication. If you don’t have yellow, you can use white or black candles, too. (There is also a new moon 
this weekend which makes it the perfect time for a spell like this.)
Silverbear’s Mercury Retrograde and Difficult Communication post seems to be highly recommended, as well.
By the way, welcome to the Spells8 community!
