They call consecutively, maybe 3 times in an hour timespan.
when I try to return the call, a recording comes on and says goodbye.

I called it back and a gentleman answered and said thank you for calling key bank

these people called me 3 times in less than 10 minutes.the third time I told them to knock it off and stop calling me as I didn't know who they were and was not interested.they never leave message or identify who they are.

I am extremely annoyed that this number has called me about 7 times in since 11:19AM. They don't leave a voicemail and if they call again I am telling them to stop. If they continue to call after that I plan on calling the cops and asking them to put a stop to it.

I got a hold of a website you can report these numbers to. It's the National Do Not Call List. Type it in google to get to the website and register your number, up to 3 phone numbers. The people who make these calls have to check this list every 31 days and take your name off their list if your number is on the National Do Not Call List. If after that time you still get calls from these numbers, there is a place on the website to take further action.
