Having just had a chat with a large appliance retailer regarding non delivery, I was told they tried (they didn't). When I asked if they could ring me when it was on it's way, I asked if they withheld their number, which they do. As do the GP's surgery, most NHS numbers, and other large companies with nothing insidious or underhanded to hide (although I see why debt collectors and their ilk may do so).
In this day and age of caller display, and most peoples phones set to either not allow with-held numbers (including mine), or people call screening and not picking up with-held numbers, why do they continue the practice? Apart from if you have to contact someone who could harass/threaten you if they had your number (ex, abusive family member, etc.) why would you with-hold your number to all and sundry, if you are someone with a genuine reason to need to get hold of them?
Or should we all hide our numbers and make it into a kind of Russian Roulette of answer/not answer?
Interested in other peoples take on this, especially the issue of large companies/public sector with-holding their number.
