Phone is trying to be hacked

I received a phone call and it said your apple phone is trying to be hacked, call apple support. I call apple support and they ask me do I know someone from New Mexico or California and that they are trying to hack my phone and that I need to go to a store and buy a prepaid apple verification card in order to wipe my phone clean. I think they interjected my call to apple support. Is my phone safe and what should I do to protect my information? They keep calling me
