Freezing LRC and photo corruption on the hard drive

I have been having difficulty getting help with a problem in LRC.  Here are the details, a bit long but for the sake of completeness, please bear with me:

Experiencing a problem with freezing, contacted Adobe Customer Care.  Finally the agent brought in an expert.  After sharing my computer and having me re-start my computer a couple of times, we got disconnected.  Received an email about the disconnection, was asked for my contact information.  In the meantime I signed into the chat again, was connected to someone who seemed to be quite competent, but still did not find a solution.  Saying more research was needed, and that I would get a phone call to re-connect, but never followed through.

Now I am getting emails from Adobe Customer Care with suggestions for what I should do to see if the freezing problem would be corrected.  The first one was to use the cleanup app, which did not correct the situation.  Then it was suggested I create a new catalog and import the previous catalog into it.  That was a disaster because now I have a lot of corrupted photos on my hard drive and the freezing was decreased for a while, but then got more frequent again.  

Since the new catalog disaster, I have been getting more emails with suggestions. Finally realized that I was being contacted by multiple people just throwing in ideas without feeling at all invested in my problem.  And some of the suggestions were difficult to understand, and appeared to be irrelevant.

The cleanup of my hard drive is time-consuming and should never have occurred.  I would appreciate help from experts, have in fact asked for that multiple times in answer to the emails.  Those requests have been totally ignored.  I hesitate to sign into the chat again because that won't get me what I need without having to first deal with someone more competent at a basic level.

Any help with getting the help I have requested would be much appreciated.
