Thanks for reaching out to us!
Sorry to hear about your situation, but unfortunately there isn't a way to provide you a backup copy of your text messages.
If I cannot get the actual text messages back, is there a way that you guys could send me a log file or spreadsheet of them? Even if it's raw data? That way I would be able to pull the relevant information out and store it somewhere else.
Are you saying that you guys do not keep a backup of the data? Do the text messages only live on the phone and not in your system at all?
