My better half phone Virgin Mobile to see about upgrading our daughter's phone as a little surprise. Wife is main account holder and daughter has a basic payg attached to the main account.
After getting the information she asked for she asked for time to think about the options and to discuss with me.
Half an hour later the Pushy Indian Lady phoned my 10 year old daughter direct.!!!
I suspect the whole Christmas, surprise thing went over the lady's head because of cultural differences. I doubt if that would have happened with an operator based in the UK, no matter what their background.
