Called a few times at different times of day, hung up when call answered. Final time they actually stayed on the line and the woman said they were window washers and would be in our neighbourhood and asked to set up a time to come by. When I told her we weren't interested she cut me off by hanging up. Call display read Di.Pr.
Got calls too. Sounds like a phone bank. You can hear other people making calls in the background. Couldn't get through on this number. It's my guess they hang up because you don't sound like a senior. These calls are all scams I would most certainly bet.
