I've had a case of someone walking into a Verizon store and buy 4 new iphones and charge it to my account. The amazing thing is that between phones, tablets and hot spots, my family has 7 mobile devices. The perpetrator did not upgrade any of the existing phones, but created 4 new phone numbers. This should have been a huge warning sign. I'm 100% convinced that the person at Verizon was in on this. In addition, over the next few days, they've made thousands of dollars in international calls. To Verizon's credit, they were great at resolving the mess for me as an individual customer, but in the end they ate the cost, which means that it got diluted to all the customers.
