I have had a CitiAadvantage card for years with Citibank. On XXXX I was told the bank declined my card. They have made no attempt to contact me, and when I check my account online it still shows that it 's open, and current with no overdue balance. I have tried repeatedly to call Citicard customer service to find out why, but they say they can tell me nothing. After several tries to reach upper supervisors ( and being hung up on once ) I was told it was " a security issue '' and that the only way to get a response was to mail them a letter and wait for a response. If there are security issues with my account or credit, I need to know in real time. Apparently there is an " executive response unit '' from which this information is mailed, but there is no way to reach them except by snail mail. The company 's refusal to provide me any information is unacceptable, and puts both my financial security & credit at risk.
