800-684-8429 calls my cell & leaves no message. There is no one on the other end to talk to if I pick up. When I searched 800-684-8429 I got results linking the number to HSCB and Household Bank 140 Industrial Dr. Elmhurst, IL 60126. I have no debt accounts or other reason for them to bother me. Since I'm already registered with the Federal DNC I will direct a complaint there as well. Michelle in California.
