got the call

whose number is it

Received a call on my work mobile of all things.

When I answered, an automated message had already started the sales-spiel about a trivia-line, saying my 'account' had been credited to start playing.

I use it for work-related stuff, but never use it in general public/web-pages/competitions sign-ups for this very reason.

I got a call and the spiel about free call credits, all you have to do is answer the trivia q. Listened for a bit before hanging up, Didn't press any buttons.

I got a miss call of it.
Then I call back through my landline. It hang up after saying "goodbye". What is the hell?!
I would wonder what will charge to my landline account??

I didn't press any # coz I new it was false!!!!
Stupid questions.I am just hoping that i was not charged for answering the call.
