Rental property address does not exist on Zillow - how to add?

[Zoe Mercier]

Has anyone else here dealt with the following?

I use the rental manager to advertise and collect credit/background checks and am trying to help get my Dad hooked up to use it, as well. However, his property (a quadruplex that's existed since 1974) doesn't show up. I contacted Zillow about it and at first, was told to just use the rental manager to see the listing. But they obviously didn't understand the issue. So I explained again and then was told this:

"When a listing is not available on Zillow, it is because we have not yet gotten the information from county records on that particular address.
You will not be able to claim this address on Zillow as it does not exist on our platform at the moment. However, I have gone into your Zillow Rental Manager account and created a listing card for your address that will then create a temporary listing for your property on our platforms for rentals." 

So we did create the listing but it doesn't show up in searches or on the map so why should be pay for that? And it's not showing "at the moment" but it's not new so we don't think it will be added. Of course, I asked them to help me resolve or at least just tell me HOW but they haven't responded. So, I decided to post the issue to their Facebook page. I'll include here what I posted because it kind of further explains our issue:

Hi Zillow. I am having an issue using your service and haven't gotten very satisfactory responses in trying to address it through emails with your customer service. Can someone help me? The problem is that when we went to use the rental listing service, we found that the property does not exist on Zillow despite the fact that we own the building and it has been there since 1974. We can't get the address to bring up the property and the address doesn't show on the map. We were given a "work around" by your staff as a link we could use to create the listing but how can be sure that the property will show up in searches? 

We were told that it not showing up because Zillow hasn't gotten the update from our local county records. Is there a way that we can try and prompt the county records to update you to include our property address? Since this building has been there for many years it seems like there is no reason that is should not appear other than some clerical or input error somewhere. It's hard to imagine that it "just hasn't been added yet" and will be added since it is not new. We feel like it might take some intervention on our part to ensure it is added so that we can claim it in the Zillow system and use your services. Can someone please advise us on how can we get this fixed? We use the service for our other properties and it would be very inconvenient to have to switch to another service just so that we can keep track of everything in one place. We WANT to use Zillow to manage our properties. Please help us to do so. Thanks!
