Who called from 4438781899

no message. assumed to be spam

Same here...called and did not leave a message.  If you can't leave a message then you're not an important call and will never be answered.  It must be a prank call looking for credit card and/or personal information.

Rang 2 times. Picked because thought it might be one of our DR'S office. No one on line. Came up as missed call. Will Block it!

Adding got called here also July 14th
Caller ID Said Columbia Md
missed call .... I've disabled answering machine .... far too many of these kinds of calls daily .... from lower credit rates, to IRS payments, to MS Virus, to Xarelto, to Medicare switching (Aileen Harris please check DNC list!) to buy your electric from spamINC

Have received several missed calls from that number but it never rang and if I call it back no answer so must be a scam.????
