mm, it does worry me this sort of thing, these companies having all your personal info. I won't be doing it.
I am very annoyed with Barclays at the moment, they keep ringing all the time, asking for hubby,(he is always at work) they ring during the day, late evening, at least once per day, I asked them what it was regarding and they said "just a courtesy call" I bet as we only have a basic bank account, they are probably trying to sell him an overdraft or such (if only they knew we were bankrupt!) I asked them not to ring again, said he was not interested and they said they would take our number off their system, guess what? THEY ARE STILL RINGING AAARRRGGGGGGGGGGGGGGGGHHHHH Wish I had given them a fake phone number when I opened the account!
