On 5/31 a caller with a strong foreign accent called saying that there had been a settlement with a company that I had done business with -- did not name the company -- and that I would get a refund of $375. I hung up on the caller, but he persisted in calling repeatedly a great number of times. After the second call, I checked the ID. It appeared as "Private caller." After that, I lifted the phone and hung up to break the connection. After about a dozen of these calls, I let the answering machine handle the call and got about five minutes of the most vile insults. Since then there have been no such calls.
