Request to remove comment of phone number

This number called me up yesterday. She said that her name is Sharon from GSM Australia. At first, I felt that it's legitimate. But later on in our conversation, she's asking me about credit card details and she is forcing me to pay USD950. When i told her that I am a bit hesitant with what she is doing, she then transferred me to a man she said is the manager, names freddy. Oh my! HE IS FORCING ME TO PAY USD950 right there and then. I told him if its ok to pay thru paypal which is more safe, and he said that its NOT! and forced me to give my credit card details.. ohhh thank goodness i didn't give in to what they wanted. SCAM!!
