Removing the 1571 call feature

[#1]

Hi, I've been trying to remove 1571 this afternoon but have failed.  I know where to go to do it (Call Features tab), but there isn't any relevant button to clock on to remove 1571 as a call feature.  I guess this is because it's not an extra and is free.  I've got a good ansaphone on my Philips phone which I prefer to use as I always know when messages have been left.  With 1571 I don't get this, and I'm missing important calls re my health as my GP always withholds his number, so it doesn't show up as a missed call.
Can someone help me please?  Thanks in advance.
Jean

Hi Jean
When you press the call features tab just below it there is remove call features underlined, click that and you can tick the box to remove voicemail

Yes, I've tried this but when I click on the remove call features, all that comes up is the caller display button.  I don't want to remove this.  There is no option to remove 1571 as far as I can make out.

You have to raise a ticket to request removal.
