Half ring, hang up. Usual scam call. Normally add to phone blacklist, but doing research to find where call center is in order to notify FCC at https://consumercomplaints.fcc.gov/hc/en-us/requests/new?ticket_form_id=39744
phone didn't even ring, so they must have hung up immediately. I have gotten those calls from people claiming to be lowering my credit card interest rate. I have told them not to call (for all the good it does) so maybe this is a step in the right direction? ha.
