I have a Citi HH reserve ($95 fee, posts in November) I did not product change in time and citi will not allow product change, I can only cancel. They are likely selling to Amex, and it will be converted to an Amex Hilton Surpass by 2018.
I recently applied and already have an Amex Surpass card, my only Amex card. Considering just closing the citi card at this point. My other option would be letting it change to Amex and then downconvert to no fee Amex Hilton. But, I’d have to call in again and argue for a fee refund, which they provided no options last month when I tried to product convert. (This would be calling After the fee posts Next month, though)
