You may restore your contacts from a previous backup. Also, you may sync your contacts from one of your accounts (hotmail, outlook, gmail)
Only time I have heard of contact list issues was when there were problems with IM (Instant Messaging Apps) like MSN, Gtalk, FB Messenger, etc..)
Your girlfriend losing her contacts with Whatsapp has nothing to do with BlackBerry as Whatsapp grabs your contacts and syncs them with their database, and is not applicable to this situation. Your GF can contact Whatsapp directly.
There are no downloads or fixes for a contact list that has been deleted. You can either restore from backup, or sync your contacts from an online service (outlook/Gmail).
Before that I would see if your contacts are not saved under an Unknown Address Book, or that you are viewing the correct book. I would even tell you how you could this, but I don't know what model you have and what OS version you are running.
