Without notice or prior warning, Citi closed my credit card account. I had no balance and was a faithful customer for over 15 years. Upon learning this I called the morning of XXXX XXXX to dispute this decision. I asked to speak to a manager and was notified I would receive a call within 24 hours, perhaps the same day. More than a week later, I 've heard from nobody. Poor service and treatment of customers.
