My husband began receiving voicemails on our landline, very garbled but indicated they were 'greendot' company and that they had a substantial prize for him. These calls had no caller-id info provide, only unknown number, unavailable name. We had anonymous call blocking added to the line. Now we are continuing to receive the calls but with the number above provided in the caller-id. 'Jennifer' identifies herself in the voicemail as an employee of Global International Bank and she has a check ready for him if he will call this same number
