Who called from 3136625080

I am sure it is a scam.. for me.. the 313 is a believable area code.. Detroit.. the 263 is a local number.. so want to answer.. but didnt.. i set these numbers up on my contact list as a donotanswer5281.. just in case they call again.. I do not have a block feature on my tracfone.  just an fyi.. annoying because they call my cell.. i give my cell phone number out to noone but family and friends.

Called me today and asked to speak to head of household. I asked who is this they said  I have no message thank you goodbye and hung up.

called asked for Raymond told them no one here by that name ,said they were collecting for breast cancer reasearch ,i let them go through there speil then told them I would give 20.00 ... they just wasted .49 cents   marked as  do not answer on my phone ..

Called four times in two days with no message.
Number blocked.
The end.

Receiving several calls from this number, just let it ring. They will give up after awhile!
