I periodically get phone calls from these idiots. They change their number so blocking them doesn't work. When you call it back you get a recording from a woman giving you 2 options. 1 for call back and 2 for don't call me again. 2 doesn't work. Have no idea who they are but they need to go F themselves.
Female caller leaves number on handset. Call back # get 2 options. One is leave a phone # and second is remove from list. Nobody calls back. Annoying scam.
