Would it be possible for the O2 Community Management Team to ascertain if the number referred to is indeed O2 or any third party authorised to represent O2? The issue seems to have been raised before but there is still uncertainty. Perhaps @Marjo would be willing to look into it?

A tip I picked up from here works quite well if you don't have call blocking: add the number to your contact list then set it to go to voicemail. Works on my Android MotoX.
The other tip is to set it to ring a silent ringtone for the caller. And work wonders why they can never contact me
