Who called from 3143620000

Just got a call.. It's 12:45am why are you calling me at that time of night? Especially since I don't know who you are.. Weird.

Received 4 calls back to back on my cell phone number this morning; no message left in my voicemail. This2- 314-362-0000 appears to be a Washington University Medical Center number but the operator @ the medical center stated that she could not help me it is a general number and she would need more info. She asked if I see a doctor there; I do not. This of course is very
annoying on all levels!!!!!!!

They are taking payment for a doctor's visit I had.

prescreening for up coming MRI, had date wrong on when I was suppose to have procedure done and wanted date of birth and social security number.

Anyone can project any caller ID or caller ID name they want.  Don't always believe what shows on caller ID.  Same goes when you call it back.  A scamming company can always answer a call with any name and scam you.  I don't live anywhere near St. Louis nor have I ever contacted any physicians group anywhere around that area.  I believe it's an attempt at fraud.
