I am a Citibank employee and I work for the Citi mastercard section of Citicorp. The PRISM/CBSD card is a conversion card from an older account you have had in the past. This account could be a number of things let me give you a few examples. Goodyear, Macys, Sears, Citi Platinum visa/mastercard, Bailey Banks and biddle, Zales, Shell Oil, Texaco, ExxonMobil. This is an ongoing thing with Citi bank. They are converting older accounts that have been closed to a new Citi Mastercard so that you have more purchasing power and you are not limited to the Retail store of your Retail Private Label card ie. Zales, gordons, Bailey Banks and Biddle, Childrens Place, etc. Any company has the right to close your old account and reopen a new account as long as you are notified in writing and also as long as they do not inquire on your credit report. I take hundreds of calls a day from upset customers about this I would like to inform you that the person taking your call is not responsible for the opening of the new account, as a matter of fact the first time the customer service agent has ever talked to you will be when you call in. You can make your call very pleasent by calling in and simply saying I would like to close my Citi Mastercard account. You DO NOT have to verify any information, as long as the representative has your account number. Also, the phone number is listed on the back of the card to call in. I would like to apologize for the fright this might have caused you and the torment with having to deal with the automated system on the phones. The best times to call would be early in the morning EST. or after 9PM EST. Citi Mastercard customer service is open 24/7 for out valued customers and I do hope you decide to keep the account open with us. One more thing I would like to mention is the promotions only found on this cars. Any purchase over $99 is going to be put on a 90 day no interest thats 0% apr for 90 days, and any purchase over $299.00 is goig to be placed on a 6 month no intrest promotion. Thats 0% APR for 6 months. If you have other charge cards you can charge your purchases on a different one and save some money because the APR on the Citi Mastercards are a little high; however, if you have any charges over $99.00 you are going to save money because there is no intrest for the specified time. If you have any questions feel free to call in and ask in a nice manner and I as well as any of my other colleagues will be more than happy to assist you.
