7th Semester Transcripts

I am very desperate right now. So today is my deadline for partial transcripts. I sent mine through my school about two weeks ago. I sent it with a friend at the same time. However, the school portal still says that it did not receive them. I called the school to ask about the transcripts. They told me that they were 3 weeks behind. I am very worried. Should I resend or just wait? I feel like my transcript got lost or something. In the future how can I make sure that I don’t have these problems again? (I think I sent them out late January)
