Male caller asked if he could pay by credit card. Since there was some odd background noise, I asked him what company he was with. Said Discovery Research Group and then wanted to speak with a manager.
So, I told him to sod off and blocked the number.
I would believe this number to be spoofed.
Received called from a lady saying she was doing a follow up from my insurance Medlife. I have united health Care. She asked me if I was given advice from anyone like the Doctor or help from family to complete my previous questionnaire. Oddlly, I had just had someone to call me regarding my benefits asking questions which was just the day before. when this lady called that late and said she was doing a survey, my question to her was, "why would you ask me if I had help with my answers". She said have a nice day and hung up.
