Current and former customers of Latitude Financial are frustrated at the company's lack of communication and have questioned its data retention practices after the non-bank lender confirmed millions of its customers' personal records dating back to 2005 had been stolen in a cyber attack earlier this month.

Latitude Financial disclosed on March 16 that more than 330,000 personal records had been impacted due to a cyber attack, but days later the company warned that the breach could widen.
