My DD feels your pain. I wanted an upgrade on my iPhone. My DD offered to "Be me" in the phone to the supplier (I'm very hard of hearing and can hear just about nothing on my mobile).
In my head the conversation should have gone along the following lines
Me. Hello if like to give you some more money every.month.
Provider, Cetainly, and what would you want in return?
Me. An upgrade on my current one to iPhone whatever.
Provider. Any preference on colour?
Me. Yes, silver please.
Provider. And will you be paying from the same bank account?
Me. Yes.
Provider. It's on its way.
Oh no. The conversation included (but was not limited to)
Provider. Do you live in an area you consider to be isolated? Do you feel isolated? Do you have any mental health problems?
Ffs, I wanted a phone, not an appointment with the Samaritans.
DD reckoned it was a safe guarding issue. Yes I'm old, but I've got a bank account and I wanted to give them more money.
