Have gotten several calls from this number on my cell phone.  Rings several times but hangs up without leaving a message.

I am getting numerous calls from this phone number.  It is a recording that states I have a message in mailbox number ?? please return the call to retrieve my message.  Annoying.

Left a message that they had tried to contact me several times in the past (terrible message - fast, noisy, unclear). Calling number resulted in another noisy message with another phone number.  Did not get number, hence, did not try to call it.
