I have to accounts with Citibank. I just called to combine and the rep said no. Is this the truth or did she not know what she was talking about.
If at first you don't succeed You can still enjoy having two Citibank accounts. Combining the accounts probably wouldn't increase your combined credit limit. I think the amount of credit is more important than the number of accounts. Congratulations on getting this far already. I hope they finally accommodate you.
