I've had loads of this recently where companies or organisations call you for whatever reason: sales or responding to enquiries or calling to schedule appointments...
And when you pick up the person says, huffily: "We tried to call you several times but you don't answer your phone."
Someone called me today from Virgin Media trying to flog a TV package. I don't usually pick up but this came from a new number. When I did answer they said: "We have contacted you several times and you seem not to answer your phone." And last week from my dentist, of all things, chasing responses to a customer survey and again it was "why haven't you responded?".
As if people are sitting on the arses for eight hours a day waiting for incoming calls from sales people. I'm lucky if I can get the urgent stuff I need to do in the day for my paid job, let alone indulge people who want to take up my time trying to sell me shit.
I find it astonishing how lacking in basic human psychology people are. If you cold call someone surely its basic courtesy not to assume that they are obliged to give you their time?
