Hey @Lis62,
Welcome to the forums and many thanks for your post. Sorry for the issue with the landline number you've requested.
Since the previous number will have belonged to the previous tenant then we can't guarantee that this will have been available for you, especially if they have moved and requested to take this number with them.
I will send you a private message to look into this further for you, however, so please keep an eye on the purple envelope at the top of the page.
Many thanks,
