This is categorically not a whinge about Zen.
I've always had the landlines set as ex-directory and number withheld by default when dialling out (if I phone someone I know I'll usually lift it by dialling 1470 but I don't want companies harvesting the number automatically, the PPI [censored] is bad enough.
Anyway, I rang up to pay a credit card and was just getting ready to enter the number when their system announced it had found my details based on the number I'd called from!
I paid the card and went though to a rep who didn't seem to know about any changes.
If I ring my mobile from the landline it appears as private number.
Anyone shed any light?
