New problem with messaging

[roachman55]

I thought and was hoping the text messaging problem was fixed but still find out I am missing messages and today when wife sent message and I replied I got a message from someone with different area code and not in phone contacts saying I texted wrong person. My wife got reply with no problem but some other person did as well, that is a first for this phone and just in case you ask did she send to more than just me, no just me it was for me.
