Hi Shazzamma117,
I'm sorry for the confusion - it doesn't look like you are set up for VoiP landline services yet, so even if you did have the adapter and tried to plug the landline into the hub, you wouldn't receive a connection.
However in answer to your question, we cannot send out these types of adapters sadly, but they can be purchased inexpensively online (they're called RJ11 adapters). Goslow is correct though - in some cases we may offer to migrate you over to VoiP landline services as an alternative to fixing a fault with a traditional landline service.
I'll pop you over a PM now so I can arrange for an engineer visit for you landline as I can see that we're unable to make a connection to it.
