If they are calling your house phone or cell phone just register for the do not call list just copy and paste it into the address bar on the browser: https://www.donotcall.gov/register/reg.aspx . It's free to put your number (This is a government website).
They calling me everyday several times!!! I added my phone number to The Do Not Call about one month ago and I stiil have telemarketers call!!! They do not leave any message on my voicemail! I do not want them call me anymore!!! do something,PLEASE!!!
They call at least twice a day. When I did some research on them I found that they are a scam. They annoy until they sucker you into giving vital account infomation. Then they have what they want and steal from you. It is that simple. Do not answer and do not give account info out!
