I recently submitted an abstract to a talk as a contributed paper. I was informed, through email, that the paper was scheduled to be presented in person on XXX date. The email also said that I could look for my name on a link mentioned in the email; going to the link, I found that my name was not on the list at all. I checked it multiple times, but my name was simply not there.
I found that the time at which I was assigned to give my presentation was on the list, but with someone else's name and paper title. I assumed that this was a timing and/or update problem, and left it at that for some time. However, this was not resolved even after two days. Thus I sent an email regarding this situation to the email address that was in the email, saying that if I had any questions I could email that address. I still have not received any email, and the conference/talk is coming up in about a month. This is the very first presentation that I will be giving, and I am not sure what to do in this situation. My questions are as follows:
Did I deal with this situation correctly, sending an email to the "query'' email address?
What must I do if I do not receive an email in a few days?
P.S. As it was inquired in the question, the conference that I submitted this to is the AMS Fall Sectional Meeting in San Francisco.
Edit: It looks like the situation has been fixed and my name is now on the list. Thank you to all who offered me advice!
