Hi @reidjames,
Thank you for your post and welcome to our community forums. We're here to help.
I am really sorry to hear that you're having some trouble with your voicemail and need the PIN resetting. If you want to call then you can do so on +44 7953 967 967 outside of the UK.
However, if you'd prefer I can take a look and see what I can do for you from here. I'll send you a private message in a few moments, so please respond to that when you have a chance and we'll go from there.
Thanks,
