Trying to sell garcinia weight loss pills not interested even with a free trial

I keep getting unwanted calls 10 to 15 times a day. It's aggravating

Is this true about the pills or are they lying

The display name made me nervous--I've heard of overseas companies that can run up charges if you answer the call. I let it go to the answering machine but they never leave a message.
A comment left at another site said it was a weight loss telemarketer.  Most comments I've read say they hang up when answered.
Caller company: Asia Pacific (caller ID display).

I saw a comment on another site that said it was a "telemarketer--weight loss."  I wouldn't trust them, tho.
