Sync Issue - Problems working with Customer Support

I have a Ligthroom synching issue about which I contacted Adobe support, we went through a bunch of diagnostic steps which didn't resolve it, then someone from tech support accessed my Mac and poked around and they still couldn't resolve the issue. They generated some logs and told me that someone would be back in touch, which is where things have gone badly awry.

I recieved an email asking me to get in touch about my case. I contacted Adobe and I was told to book a call back, which I did, but no one called. I contacted Adobe and was told to book another call back, which I did, but again no one called. I've just finished another call in which I was told that someone would call me back in the next four hours - I really don't believe that anyone will call me.

I'm also getting automated emails that don't acknowledge that I've been in touch about the case and tell me that it's about to be closed.

Right now, I have a thousands of images in the Adobe cloud that I can't retrieve and a tech support team that don't seem to know what is going on.

My question - has anyone in the community experienced anything along these lines before and how did they handle it?

Thanks in advance.
