Messages with Persistent Spam
iPhone 12 Pro, IOS 27.0.1. I have persistent spam from several sources. I have blocked numbers, put in junk folder (on MacBook M4 Pro), deleted and reported to Apple and mobile phone service carrier T-Mobile. Nothing stops them. The scammer is posing as IRS agent or service to help me deal with an IRS issue that I don't have.
My iPhone, iPad, and MacBook Pro are connected via iCloud. What options do I have remaining to stop this? It's been ongoing daily for months.
