Voicemail issues for Samsung S6, any help?

[AC Question]

Voicemail issues for Samsung s6!!

I was asked to change the 3 digit code for my voicemail and stupidly put 101 - which means when I try to access my voicemail I get through to the Devon and Cornwall police. I then decided to delete the voicemail which is in my contacts thinking it would make things easier? Whenever I hold down number 1 it just takes me through to the police and I don't have any option to change it.

Any help would be appreciated
