We got a call from this number and a male said he was taking a survey and wanted to know if we lived in an apartment. After I answered, he said that was the whole survey and hung up. He never identified himself or explained what the survey could have been for, so it didn't seem legitimate.

A young man called me and said my last name incorrectly then  hung up

We also got a call, then hung up

They call every other week, but this time asked for me by my last name and then hung up...
