Called my cell phone

Didn't answer, call from 3050008578 to my cell.

I answered, finally listened to the whole recording (called every day for a week), clicked through to a live operator, asked to be taken off the list, and was hung up on.

Called my home phone. Says it's "Rachel" calling about my credit card and that I'm eligible to have my interest lowered to 9.75%. Doesn't give a credit card company name. Either some disreputable company trying to get you to apply for a card or, more likely, some scammers trying to get your credit card info so they can use it! Tried to get a live operator to tell them that I'm on the Do Not Call List, but they "couldn't take my call right now, please leave a phone number and message etc". Reporting them to donotcall.gov.
