Unauthorized Apple Pay charge and suspicious text message

text: I got a text message stating that an unauthorized purchase in Florida was made against my Apple Pay account. It gave me a description and phone number and asked me to download and install Awesun so Apple support could gain access. The logins provided fix not end with Apple.com so I hung up. It’s a scam right?
