Hi SophieBoxall,
Thanks for using the forums to get this issue with your landline services looked into, I am sorry if this has been causing some frustration. I would be more than happy to look into this for you.
I can see @Client62 has already offered a link so you can order an adaptor yourself, we can also email the local area field manager (AFM) to ask them if an engineer can drop off an adaptor for you.
Please let us know if this is something you'd like us to do if you've not already purchased one yourself 🤗
Thanks,
Megan_L
