Fraudulent phone call review: Phone call

I just received a phone call from a number claiming they were Apple services and that I had had suspicious activity in my cloud account. They said I shouldn't open any of my financials, but when I called Apple Customer a Service they told me that was a fraudulent call, and I could report it to you so that someone could follow up with it. The number that called in was 1-800-759-1325, but I also had missed another call just seconds before that at 1-800-989-2931, so I didn't know if that number was related either.

Thank you
