Did you cancel within 48 hours of making the booking? and was the booking more than a week away?
If so, even if the host had a strict policy, you should get a full refund.
Did all the messaging occur back and forth on the airbnb platform? Again, if so, Airbnb Cusotmer Service will be able to see this and it should help your case if you were outside the time parameters.
I agree with @Yadira22, some hosts have specific limitations imposed on them by their councils, or their insurance -which over rides airbnb policy. so it's possible this host does have a 25 year age restriction, but if she does it should be clearly stated in her house rules ( which you are meant to check carefully before booking. If there is something like this in her house rules and you have booked anyway, you are on less firm ground)
The other thing you need to be aware of, is that the host does not have any of your money so is not able to refund you anything. Airbnb collects your money and distributes it to the host after the guest checks in. That is probalby why your host is no longer talking to you - cancellation can really only be managed now by airbnb, there is nothing at all the host can do.
I don't know for sure of course, but I think it is very likely you will get a full refund, especially if you cancelled within the time parameters. I know it's frustrating but it might be worthwhile ringing CS again ( dont' message). Keep you language calm, direct, simple. CS is very much biased towards guests, so keep telling them how disappointed you are with the service, and how it is putting you off airbnb.
For the future, if you dont' already, it's imperative that as a guest you carefully read all the house rules prior to booking. it will be in the section "things to consider" on the left hand side, just before you book - eg no parties, no smoking, then a drop down triangle "read more". In the read more section, there may or may not be a whole lot more of rules you need to consider. It's disgraceful how difficult airbnb make this to find and read. It negatively impacts on both hosts and guests.
If the over 25 rule in NOT in this section, I can't see any barrier at all to you receiving a full refund, regardless of when you cancelled, especially if the host and you kept the communication re this on the airbnb platform. However I"m no expert, just another host.
Good luck!
