Very rude

I got a call from a woman named Portia from Afrizone which apparently teamed up with Vodacom with regards to airtime and data deals. She offered me a contract with a wifi router along with airtime and data on top of the airtime contract I already have where I told her that i do not have the need for the wifi router or another contract. And whilst I was talking to her she just put the fone down in my ear. That's just plain rude to put the fone down in someone's ear while they're talking.
