Called, left no message.

Called but left no message.

Pain in the you know what

Called and left message saying:  "Hello.  Hello"

Just called, no message.  This must be a call center or someone spoofing.  520-448-0237, 0257, and 0258 all with caller id Tucson, all have left repeated calls on my phone. They always call but leave no message.
