Who called from 8187826600

Received a call from 818-782-6600.  If you Google it, Valley Presbyterian Hospital in Van Nuys, CA comes up in the search.  Doesn't look like a telemarketer, but I wonder why they're calling.

Called me this morning, no message, called back and it was Valley Presbyterian Hospital, strange.

I was charged $2.00 on my checking acct. some how..  How did these people get a hold of my account and do this?

Received call from this number. Called back, was told it was from Valley Prebyterian Hospital, caller unspecified. Block number.

Received several calls during recent holidays . . . background noises and maybe some voices, but no one said hello and no one would answer me, then it disconnects. Reverse look-up states it's the main number for Valley Presbyterian Hospital in Van Nuys.  Someone seems to be doing something at this number that is not appropriate.  I blocked it on my phone.
