Was it an instant denial? I got pending further review notice and called the inquiry line but the lady said they were mailing me a letter requesting more info and she would not divulge anymore info. 
To my understanding there are backdoor numbers to reach Citi but a re-evaluation could potentially require an additional hard pull on your credit. Citi reconsideration backdoor number I found online: 866-336-7285. This is also called “Citi EO” (Executive Office) phone number. This phone number is not designed to make reconsiderations, but the representatives are really helpful.

With citi, it’s always best to recon after you receive their letter and cite the application/reference number when making the call. They mail it to the address listed on the CRAs so having possession of it can also serve as a security check for them plus it might also just be a letter requesting for more info or documentation that may be needed for further review.
