Citibank Debt Collection Complaint

Citibank Debt collection department,

Credit card Communication tactics Frequent or repeated calls Indiana

They call every - min at least - per day. I work during the day so I can't leave to pick up my personal cell phone everytime my phone rings. I have told this company before that it is to the point of harrassment since they call so frequently and NEVER leave a voicemail with this specific phone number. I have told them before to leave a message and I will get back to them when I am free. But they have not honored my request. They said it's an autodialer and they can't control it. That doesn't make sense at atll! I would love to call them every - and hang up-see how they like it! Ridiculous!
