Caller: Someone claiming to be from Visa

Definitely a scam. A man said someone was attempting to use my visa card overseas but they had put a hold on it as it looked suspicious. Sounded kind of legit until he asked me to download an app called zoho assist. When I told him I couldn't he wanted me to delete something from my phone so I could. I hung up. Of course it was all a scam and my account was fine.
