It prob hasn't yet, but still could. Many times this next visit is a 2nd-investigation/give-counsel meeting. In other words, they most likely are being sent to give you stern counsel, warnings, share scriptures, pray, yada yada in order to "readjust" you.
Yes, exactly. They are oblilgated to visit you at least twice, per the Shepherding book, using this scripture out of context:
As for a man who promotes a sect, reject him after a first and a second admonition, 11 knowing that such a man has deviated from the way and is sinning and is self-condemned. - Titus 3:10,11
Once the second admonition is given, if you don't respond, they can form a judicial committee. Of course, you are not promoting a sect, which is why this is an out of context application of this verse. In addition, verse 9 talks about "foolish arguments, geneologies and disputes and fights over the Law" which is likely not what you are doing, either.
