Who called from 4243545100

Same as a few others. Very think oriental accent - almost unintelligible. Asks if anyone in my household has diabetes. At first, I though she asked if anyone in my family died!  I have told her to remove my number from her call list. We'll see what happens.

Caller with thick Asian accent kept saying, hello, is this a business?  I asked their name and they repeated, "is this a business?"

received call from this number numerous times..no message after answering, just robo  'good bye'.
caller id shows the strangest yet ----ready----u06020036150614.  don't know; don't care; don't answer.

Asian accent - ask for my x husbands wife ?  told her she had wrong # and just rudley hung up.

Just wonder if these people are getting numbers from Craigslist?  I know they fish for email addresses on there and think they go for phone numbers also.  I have gotten 2 calls from these people today.  Caller id says number and California.  I didn't answer and they didn't leave a message.  Very irritating!
