Who called from 5623710938

Called my cell.  Did not recognize number, no message left.  Number blocked.

7/31/17 13:13 PDT  Ever since I requested info regarding senior in-home care, I have been receiving call from "local" number which I don't recognize and they leave no messages.  La Habra is one of the IDs they use and I will not answer any call from these creeps.  No valid ID and no message earns blockage.
