Dear Daughter:
We doubt that you will be able to get the letter back before the scheduled interview date, which we presume is July 11.
If your mother still wants to attend the interview on that date, she can appear with photo identification, and explain what happened with the original appointment letter. INS should be able to check their list of scheduled appointments to see that she is scheduled, and she can go ahead and attend the interview. Good luck.
