College transcript

Hello,
So my school send my final transcript to UCR. However, on MyUCR, it says that they have not received a transcript on my high school. I went to the FAQ section and saw that they say “Our office receives a high volume of official documentation per day. As a result, it takes approximately 3 weeks to process your final transcript before you can view this information in your MyUCR account.”
Final transcript is due on 7/1. How do I know if UCR received my transcript but did not change my status, or something went wrong during the process and they did not receive it? Parchment says that UCR successfully received my transcript on 6/20, but I am still worried, since after 3 weeks it would be long after 7/1, and I might be in trouble if something actually went wrong.

Call admissions to confirm the receipt of the transcript.
