Got a call from +1 (650) 947-2770 (official number of some police dept in CA) about my Masters being under IRS audit due to some irregularities in the payments. I tried hard to understand their voice, but something was wrong in the network and their voice kept dropping. The woman speaking to me finally got frustrated and cut the call. I called back and spoke to the reception and the lady there told me that scammers have spoofed their phone number and are using it to scam people. I guess there's some benefit to AT&T giving bad service around my office?
