Answered and it was a machine telling me they were from preferred credit cards. I could barely hear the message and it said something about lowering my interest rate. Scam. If you call the number back there is no number available. Just scammers who have a piece of hardware to show any number they put in on your caller id. I blocked them now, just be aware. this company isn't real and they cannot get your credit card interest rate down. Need a way to get your interest rate down? Pay nearly double your monthly minimum payments for 12 solid months and pay always ahead of the date due. After 12 months, call the credit card company directly and ask for it to be reduced based upon your activity over the last year. If that doesn't work, find a better credit card company and see if you can roll over what you owe to them and again, make double the amount due payments and then ask for them to lower it even more after a year. Don't fall victim to the phone calls stating they can get your credit interest lowered as all they are trying to do is get your credit info so they can steal it and steal your money and identity. Just hang up and buy a block box from amazon. Call blocker box for landline. If on cell phone, either get an app that can block calls or more likely your phone can already do it.
