We received several calls from this number in the middle of the night on both our cellphones. When we picked up, a "young" girl just kept on repeating what we are saying till we lose patience & hung up. Then another call & so on. We traced it to a landline in san Pedro, CA.  We called back several times & a lady picks up then gives it to the young girl who initiated the calls.  What surprised us is they know all our numbers.
