Dh had no end of ‘pester’ calls after he made a charity donation via his phone.
For this reason I won’t donate by phone - I’ll donate via the website instead, and if they ask for a phone number they will be disappointed.
If any online shopping sites insist on a phone number, I just make one up. Why they insist I don’t know - you invariably have to give an email address for confirmation - why won’t that do, if they need to contact me?
The one time I did give a phone number, years ago now, was after I’d ordered something for next day delivery. And guess what - I waited in all day, it didn’t arrive, and they didn’t phone to tell me why.
Next day - ‘Oh, sorry, it was unexpectedly out of stock.’
‘So why didn’t you phone me then, having insisted on a phone number?’
They couldn’t answer.
Still, I wrote a stiff letter of complaint and received a £30 voucher, worth rather more then. So it wasn’t quite all bad.
