Old Texts Deleting

[Theframer]

My Galaxy Note 4 has a habit of deleting all my old text messages. Annoying, some of my customers still use texting.
In the message settings I have the 'delete' option set to 'off.' They still get cleared.
Any ideas please? Thanks in advance.

I think you need to consult the customer support.
