I missed the visa interview call from the American Embassy. Will they call again? emigrant

If there is a caller ID, you can find it. If it is a phone call from the American embassy, in order not to delay time, you can write an email to the embassy, saying when you received the phone call from the embassy and asking what it was! If your phone is down, and you are not sure whether to call you, just write to the embassy, stating that your phone is down or your new phone number.
