I signed up for a new promotional offer from XXXX XXXX XXXX XXXX XXXX ' credit card offered by CITI Bank in the month of XXXX 2015. The promotional offer was for purchasing a new phone from XXXX XXXX XXXX ( Using the link provided ) and then get a refund up to {$650.00} as a statement credit. Below are the details of the offer ( Also available at this link : XXXX Offer details ( Copied form the link above ) : -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Spend {$2000.00} in purchases with your XXXX Card within 3 months of account opening. 
Use your card, now or later, to buy a new phone from XXXX XXXX XXXX, at full price and with no annual contract. 
Make your phone purchase using your unique phone offer link ( which will be provided to you ), activate and maintain service with XXXX XXXX XXXX for 15 days. If you buy a new phone now it will count toward the {$2000.00} in qualifying purchases! 
Citi will then credit your XXXX XXXX XXXX XXXX XXXX XXXX account for the cost of the phone up to {$650.00} ( exclusive of taxes, shipping, fees & wireless service ). 
Phone Offer Credit is not available if you have had an XXXX XXXX XXXX XXXX XXXX XXXX account that was opened or closed in the past 18 months. 
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Now, I made more than {$2000.00} in the first three months and also purchased a new phone using the offer link from XXXX XXXX XXXX. I fulfilled all the required criteria to be eligible to receive the {$650.00} statement credit. But unfortunately I did not receive the {$650.00} statement credit. 

I tried to resolve this issue by calling their customer service many times, but the issue remain unresolved. Initially the customer support executive told me that the credit will be applied to my next statement but the credit was never applied. 

I have all the necessary proofs and I will provide them if required. 
Thanks.
