The CEO of Cellcom confirms a cyber attack took down its voice and data services last week. CEO Bridget Rirden made the announcement in an unscripted YouTube video on Tuesday. She says there is no evidence to show that personal customer data like payment cards, bank account information, or Social Security numbers have been compromised. Rirden says tech crews have been brought in from around the country and they expect to have the rest of service restored this week.  Most Cellcom customers have been without voice service to non-Cellcom phones since last Wednesday evening. Some services were restored on Monday including voice calls between Cellcom Customers and SMS messaging.
