how are you in arrears - have you stopped the DD - thats rule number 2 - never do that - VM systems may not be joined up but owing them money kicks in dept collectors and black marks on credit ratings - so get that sorted before their only efficient system kicks in
as to internet next door and you cannot get it - thats possible - is the house new or more exactly was in built after the VM or earlier company laid the duct - i have that - i am the last house on the duct laid 20 years ago - a new estate built 10 years ago cannot get VM - nect door is literally that 8ft away but they cannot get VM
if you are in that situation you might get them to connect to next doors external box - a bit more complicated and they should look for permission from next door - all depends on how the run would be - wait for staff and they may be able to help
