0844 507 5655 - Plusnet Customer Support Number
I contacted their customer support through this number and they were really friendly and helpful.
Depends what you're after really?
The information here should help though - www.plus.net/home-broadband/contact...
If you're calling from a landline then use our 0800 number (it's free). If you're calling from a mobile then use the 03 number (it's taken from your inclusive minutes, 0800 numbers cost from mobiles).
Alternatively, if you're an existing customer then you can use the ticketing system/Help Assistant available on our website at contactus.plus.net
If you've a problem with your broadband connection then you can report a fault as faults.plus.net
Hope that helps.
Plusnet Digital Care.
