Who called from 2126704869

I received a phone call from this number at 3:58am saying it was Bank of America doing a Test phone call. I proceeded to call Bank of America and they denied everything.

They called me at 3:15 am today as well.... Reporting the number!!

I got a call, waking me up, from this number at 1:40 a.m.  Called the number back and it said it was Bank of America testing the line.  The caller ID said MERRILLLYNCH. What the heck?
