Number withheld

[#1]

After some problems with a rogue dialler, my phone service with BT was set up with a permanent 'withold number' facility. When I switched to the Post Office, this facility was automatically transferred to my new account. It has recently become apparent that I don't have this facility on my Plusnet Home Phone account.
Can this be added? Will I be charged extra?

Hi Maranello,
We can do this for you and we wouldn't charge extra for it.
If you raise a ticket on your account asking for it, give me a poke and I'll make sure that it goes to the right person.

Thanks.
I've passed it on to the relevant team.

The relevant team haven't responded in five days. Any chance of giving them a nudge, please?

Hi Maranello,
The order completed on the 25th.

Thanks James
I guess the ticket would have been updated eventually

Hiya,
We're currently unable to place an order until the broadband order is complete.
Once your broadband order is complete, we'll place the order to withhold your number.

I'm a little confused by this exchange. I'm on Home Phone and my understanding is that if the Call Barring Feature is required it costs £4.00 monthly. Is that right? If it is, does that cost apply if one simply wants 'withheld numbers' barred? And if it does, why is it so expensive? Why is it the dearest Call Feature and four times the cost of Caller Display?
My interest stems from a sudden surge in calls of this type, despite being registered with the Telephone Preference Service.

It's basically because it's one of the most expensive feature that Openreach offer on WLR (Wholesale Line Rental.
