Citibank - Citigold Checking Account Promotion CASE Dispute # XXXX I was enticed to avail a promotion of Citibank branch located at XXXX XXXX XXXX XXXX. XXXX, CA XXXX. The promotion is you earned {$600.00} bonus if you open an account for {$50000.00} and maintained the same balance for at least 90 days. It was XXXX XXXX an account officer of Citibank in XXXX, CA who explained to me the details of the Promotion. 
I was asking for the promotion code from the account officer but was told that she would just put a notice of the promotion on the reference or note field in their computer system. 
I opened the Citigold Account on XX/XX/XXXX and trusted XXXX XXXX of Citibank XXXX, CA branch regarding the promotion of {$600.00} bonus after maintaining {$50000.00} for at least 90 days even there is no promotion code and just a notation on their computer system. I went out of the country ( XXXX, XXXX ) since I opened my citi checking account. After more than 90 days I checked my Citi - checking account online and noticed that the {$600.00} bonus was not credited. I complained by overseas call to Citibank 24 hour online banking and spoke with a citi - associate ( XXXX -employee # XXXX XXXX ) and was told that he saw the notation of the promotion of XXXX XXXX and subsequently told that the promotion should be validated by the branch where I opened the account. He forwarded my complaint as well to XXXX XXXX of Citibank XXXX, CA. The following day XXXX XXXX called me back and was told that they need to forward my complaint to Citibank Head Office to validate the promotion and was given a dispute no. XXXX initiated on XX/XX/XXXX. As of this date there is no resolution yet regarding my complaint and its past more than 90 days already. I attempted to call directly XXXX XXXX XXXX of Citibank XXXX, CA branch but my call cant get through the recorded message just keep on routing my call to a call center. I decided to file a complaint again my means of live chat and they forwarded my complaint again to Citibank - XXXX CA branch care of XXXX XXXX who called me the second time around. She told me that Citibank Head Office is still validating my complaint??? and because of the delay regarding the promotion bonus they are giving me a XXXX reward points which is equivalent to {$100.00} gift card of my choice to be credited after 4 banking days. I ask XXXX XXXX to email me our verbal conversation so that I have proof of what she promised me. She verified and confirmed my email on file and was told that she will email me after our conversation. To make the long story short after 4 banking days I did not received the XXXX reward points as well neither an email from her indicating our phone conversation regarding the promotional bonus and the XXXX reward points. I subsequently filed a written complaint ( XXXX XXXX Ref # XXXX - XX/XX/XXXX ; XXXX XXXX Ref # XXXX XX/XX/XXXX ; XXXX XXXX Ref. # XXXX XX/XX/XXXX ; XXXX XXXX XXXX # XXXX XXXX/XXXX/XXXX. Since I am outside the country and so skeptical with the transaction deal that I am encountering with Citibank, I requested them to block my Citigold Checking account for security purposes. I am now planning to return back to the USA as soon as possible and withdraw my all money but my problem is I might loose the promotion bonus and rewards points that I am entitled???? Please help me resolve my case with Citibank. I exhausted all ways and means to deal with Citibank but still no resolution to my case. My overseas cellphone no. is XXXX which is also on my file with Citibank XXXX, CA branch.
