I'm sorta lost with Appen

This is my first week and I'm confused how things work. My work is basically just saying phrases from a prompt and recording them. It said I need to finish it at the end of the week but they sent the email on a Friday. I was able to finish the all the prompts but on the Sunday of the same week. I checked the timesheet and other things but it doesn't say anything on it?

I'm sorry if this seems like a stupid paranoid question (well, because I sorta am) but hopefully a few of you will answer me. Thank you!
