Just got a call from this number, I answered, said hello but got no response and then it went silent and was hung up on, I then called the numebr back and said I would like to not receive anymore calls from this number by pressing 9. Telemarketer, scammer, phishing or something not good. Maybe they were looking for someone of a particular age to take advantage of?
Called phone number back and got a recording that it was a survey and that it expired - gave me the option to press 9 to remove my number from their call list. Hopefully pressing 9 worked.
