I got the call today. It is from "Cardholder Services." That is a dba for a company called SBN Peripherals. It is a California Corporation located at 3230 Cornell Road, Agoura, California, 91301. The California Secretary of State lists the official contact for the company is Hans J H Smit Duyzentkunst. His telephone number is (818) 879-9994. He denies having anything to do with the company. But he is listed as the official contact by the state. You could call him when you get a call from "Rachel" or "Tiffany."
