Block Withheld Phone Numbers

[jjjamie011]

Hi I need to block withheld phone numbers coming to my phone, how do i do this?

[aiya_x associate]

you'll have to call up the phone company and see if they can manually block the number that's phoning you. not sure if it
will work since it's a withheld number but it's worth a try

Giffgaff can't put a block on private numbers, the only way to stop them is to change your number! Or if you have an android phone there's free apps available to block unknown and unwanted numbes

If you're getting nuisance calls you can have your number changed. I'd only recommend this if it's been going on a long time though.

if youre on an iphone and youre willing to jailbreak theres an app called iblacklist which does that amongst other things also i believe certain other phones have the functionality built in...

Unfortunately this is beyond giffgaffs control and they will be unable to assist you.

I think they will be able to help you as if you look at the terms and conditions,

18.1. You authorise us to use and disclose, in the UK and abroad, information about you, your use of the Service (including, but not limited to, phone numbers/email addresses of calls, texts and other communications "Communications" made and received by you and the date, duration, time and cost of such Communications) 

Im not sure if they will help you, but they keep track of your phone usage so they should know the numbers of those calling you on a private no, so in theory, they could block them. It may be a lot of work but its possible.
