Who called from 3523903231

Caller ID says Morgan Stanley.  Called three times Friday, twice today (Monday), didn't leave any messages.  The last time I picked up and said "Please state the nature of the emergency"  Dead silence, call center noises in background, then call dropped.  Well, if they called that many times, it had to be an emergency, right?

Calls three times a day for the past week. ID says Morgan Stanley. No messages and no one talks. I'll block them if I have any room left.

"Morgan Stanley"  started calling again, so I picked up.  Female calling businesses regarding credit cards.  Told them to put this number on their Do Not Call List.  If they call again they will be reported to the FCC.

Keeps calling. Always three times in a row. No way to call back to be placed on a do not call list with company
