Who called from 6369486031

Called. Didn't Know the Number.
Didn't answer the phone.
No message left.

Called, likely a Robocall.  No one spoke.

Robocall, repeated over the past several days.  No one at the other end.

Called exactly TEN times on May 16.  I did not answer.  Today, May 17...SIX times and it is  only 2 P.M. Sometimes Caller ID reads House of Spring,MO.... sometimes reads Unavailable.  Same phone number.

After several calls over 3 days, someone finally responded to my "hello." The caller wanted to talk about my "time share" which I have never owned. Upon hearing that, the caller thanked me and ended the call.
