Unrequested iCloud upgrade billing
I just received an email which I suspect is spam. The sender is info@geek-squadservices39.co
It's a billing for upgrading my iCloud account (now at minimum and free) to 15T storage. I'm retired and certainly don't need 15T of storage.
How do I determine if this is spam, or if I've been hacked and might really get charged $1495.90 a month?
And, what, if anything, should I do about this?
I didn't see a topic that I was sure was correct for this post, nor am I sure it's about my iphone SE as I got the email on my computer. I chose those responses because they were the closest.
TIA
