Dark web monitoring feature not working

Dark Web Monitoring feature doesn't work anymore since 5 months.
When I try to enroll it I get error code 32030 or sometimes a different code depending on the device or browser, and often accompanied by the words "Your subscription expired".
Of course, my subscription has not expired and all other features work.

It all started when I switched from Norton Premium to Norton Deluxe through a chat with a Norton Customer support agent 5 months ago.

I tried with different devices, browsers, internet connections but always get some error.

I contacted Lifelock and general Norton support so many times, but every time it's like talking to tree trunks. 
No agent in the Lifelock team ever did anything except transfer the call to other agents who have even less knowledge than the previous ones.

I literally spent hours in phone calls with Lifelock transferred to at least 15 agents who know nothing about it and especially do nothing about it.

One agent even told me Norton Deluxe does not have the Dark Web Monitoring feature. Who hires these guys?

They all ask me the same things (take control of my laptop and do updates, try with different browsers and few more basic things.).
One agent asked for screenshots of the error and I sent two. They confirmed they received the screenshots but then they did nothing about it. After one month, no reply, no update.

So I contacted them again two days ago and it is like nothing ever happened, I have to start all over again explaining my problem even if I give my ticket number in the beginning.

It is clearly a bug in their system as the Dark Web Monitoring feature seems to be still linked to my previous Norton subscription (which I replaced with the Deluxe one).

They should contact someone with technical knowledge to fix this, I asked them so many times to escalate this problem but it is useless, nothing ever happens. It's been 5 months.

I don't know what to do anymore, I have had Norton for 9 years and I am thinking about leaving it because of this lack of professionalism.
I pay for this subscription and I think have the right to use all the available features.
