Caller: Scammer posing as Amazon prime

Scammer posing as Amazon prime. Asking if you want to pay $99.99 to continue with subscription. I have Amazon prime to watch movies ect but don’t use. They claim to want to refund the $99.99 asking to download an app to enter in bank card details then to check bank account to see if refund has gone into your account. I told them no. They said it was paid using my ( name of bank) card and asked me not to use my bank apps to look at my bank online acc to see if deposit made. Again nothing. They seemed to know what I was doing to which they replied no but when asked for a phone number to call them back in he became aggressive which was a dead giveaway. When I went to end call I noticed the green banner at the top of my iPhone ( usually meaning I’m on a call) wasn’t green but was red. When click on it said my screen on my ph was being shared. 🚩 I ended the call then canceled my bank cards and reported the scams. Lucky my passwords were saved and automated so they didn’t see.
They were Indian one woman who took the call and a man that was later handed over.
Be carful out there this was very clever as they even went into Amazon.com
