Gabriel Erik Olson review: stealing private customer data from t-mobile customers

Gabriel Erik Olson has worked at T-Mobile for a short period of time. He has been stealing customers personal info to resell to people outside of T-Mobile. I am aware of this due to having lunch with him once and then finding that he had written down dozens of customers mobile numbers, names, address, account numbers, and last 4 of ssn's. When I seen it his excuse was he had written everything down to schedule follow up calls. Clearly, you do not need a customers last 4 ssn of any other sensitive data to call them back. I have since decided to stay away from Gabriel Olson, I don't want his issues to affect my career at T-Mobile. After researching more into Gabriel, I found that he lived in Pueblo Colorado years ago and his family has had a history of drug addiction and run ins with the law. How this was missed while hiring him has me puzzled.
