Who called from 5035482991

They keep calling and leave no message.  When I call back I get no ring, nothing.

Called and hung up and when called back it was silent.

Receiving calls from this number at odd hours like 9:00PM and on holidays. (Labor Day 2012) Really on a holiday?

Have received many calls from this number, no messages left.  Last time I picked up, it was Card Services recording about refinancing credit cards at a lower rate.  They call late and on weekends/holidays. Today is labor day and received call at 11 am.

This number keeps calling.  AND. No answer
