As already noted, It's not a scam or marketing call, It's a security call from Capital One to give an access code for an online bank account. It's of no use to anybody but the account holder trying to access their account online and obviously people could be requiring that code at any time of the day. It's a mistake caused by an account holders incorrect telephone number, So just end the call.
This is the automated call from CAPITAL ONE, For customers that calls you back (with a code) to access your online account. If your not with capital one you should NOT get the call
This is the automated call number, From CAPITAL ONE, That calls you back (with a code) to access your online account.
If you do not have/had a CAPITAL ONE online account maybe your number has been specified on someone else's account in error. Or maybe your number belonged to someone else that had an account with them.
