called at 6:40PM tonight. Caller id: "Unavailable". I shut the answering machine off so they couldn't leave a message and they gave up after letting the phone ring 12 times.
This has nothing to do with timeshares, medic alerts or obamacare. It's all about get enough information out of you to scam you out of money. That's these scam artists goal. Either get a call blocker or ignore incoming calls that you do not know. If it's important, they will leave a message. Never ever engage a telemarketer in conversation (unless you want to f%ck with them). Even that is a no - no. They then know that your number is active and they then sell your number to other telemarketers.
Keep a sense of humour and let the robo calls go unanswered.
