unsolicited nuisance calls all day and late at night

Makes sense, we went to Rochford for a day on the green a month or so ago and they now have my details. I just got a random call from this number. They hung up as soon as answered with a standard business greeting.

A lady just said "Hello" and a couple of seconds later just hung up

No message just hangup.
