Hi mbrunn,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear you've been having issues with your landline service. When you have a bundle, this usually puts you on for a heavy discount on the package so when removing a service, it does remove the discount which is likely why the teams have advised not to do this so you're not paying more for 2 services.
Lets take a look at things this end to see what's happened and how we can help. In order to do that I will need to confirm some information with you to pass security. I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊
Thanks,
