'Sorry for replying late' and other phrases in Korean?
How would I go about saying:
1) I am sorry for replying late.
2) I had no internet/I had no Wi-fi.
3) I did not realize that you already replied
4) My school has bad internet. It did not let my messages send.
I don't know how to communicate well with my e-penpals so when they get shocked that it took me 8 or so hours to reply because my school's wifi doesn't let me access kakaotalk properly I don't know how to explain it to them. haha. But if someone could translate one or all of these it'd help out a lot! Please and thank you!
