Apple support scams
I keep getting calls from persons with heavy Indian accents saying they are from Apple support and have monitored a problem with my computer. They have me log to a website and ask me to share access to my computer. In Dec 2017 they did work to remove "malware", installed software, and had me buy a $500 Apple gift card to pay for it. I had the feeling I had just been scammed.
Yesterday they called me again. I discussed my concerns with them and they told me refund was underway. Midway through the conversation the line went dead. They called again today to tell me they had investigated my computer and the problem was in my network firewall. They asked me to but $500 if iTunes gift cards to pay for the protection they wanted to install. I told them I would call back when ready.
Is there any way to know if these people are legit? If they're not, how can I make them stop or better yet, have them arrested?
