They call and hang up as soon as I answer. This is not the only number they use.

The call rings once and hangs up. When returing the call the recording is Capital One Auto.

This is Capital One Auto Finance. No message is ever left.

This is not Capital One.  I was able to contact Capital One customer service, and they verified that these numbers in Texas are not affiliated with their organization.  They asked me to call the National Fraud Information Center at 1-800-876-7060.

This is CAPITAL ONE AUTO FINANCE in Dallas, Texas.  They start calling the first day into your 15 day "grace period" on your auto loan and if you don't answer, their computer redials every 50 minutes from 8 am to 9 pm local time until you answer.  Even when you make arrangments to pay before your 15 day "grace period" expires, they will continue to call daily until they receive your payment.
