Caller: Scammer?

I was called by this number, but then they must have realised they forgot to hide their phone number, and then they hung up and called by private number. I picked up the call the second time, not the first time. But I rarely get calls, so it's too much of a coincidence for them not to be by the same person. It was a scam call, they pretended to be Amazon, chasing after some person named Crystal who had stolen my account / phone number to buy an iPhone. I've seen enough videos on YouTube about scammers to recognise a scam call immediately. I insisted he was a scammer, and he called me a very rude name and hung up.
