Hi ColGri,
Welcome to the Community Forums, thanks for your post.
I'm sorry to hear you've been having issues with your calls.
We can see you've posted in the broadband section of the forums, so we can't gage whether you're having issues with your mobile or landline.
If you could provide some more information and let us know which service you're having issues with, we'd be happy to help you further 🙂
Beth
