Who called from 9802655633

When I picked up the phone and did not say anything there was a woman's voice and she said "Hello" loudly twice and hung up!  What is this?

I picked up the phone and a lady asked if the lady of the house was there and I said, Yes and she said hello, Susan?  I said no, and then she hung up.

Weird-O!

No message. Hang up call.

Call shows up as Breast Cancer or BCFA.  Uses different phone numbers.  When I told them to stop calling the woman on the other end started laughing.  I will report these scammers to our state attorney general's office.  I now have 20 call numbers blocked on my phone btr they always find a way around It!

Rings 3 times and hangs up
