How can I stop these annoying calls? Other than ripping the phone off the wall.

they are calling my cell which costs daytime minutes.  never had calls from anyone other than my call list before, but went to stupid makeup party for arbonne from friend of friend who got sucked into their pyramid scheme and didn't find out til after they had my number that they are a scam pyramid style company already in chapter 11.

scam
"one of 5 prizes can be yours, all you need do is pay shipping or go to a workshop selling high price timeshares" report to bbb"
gave me this number as number of supervisor to talk to regarding getting calls stopped.
supervisor name is janet.

Didn't talk once I heard the delay before someone said hello.
Caller ID said International Call.

also calls as non profit health tec survey on air quality  and attempts to skim info on pets and how long you have lived in area. haven't been able to put a fix on what the company is really doing but the call ID shows up as 3072151002
