Received a request from Citibank to upgrade my rewards card. Was bombarded with request and finally gave in. Only upgraded because I could complete the process on the internet and did not have to complete a new application. The card that I upgraded had accumulated several years of rewards that I had not redeemed. When I went in to redeem my rewards, I was informed that I had forfeited the rewards by upgrading to the new rewards plus card. Contacted Citibank to complain and they said a dispute was filed. Later received notice stating that the rewards were forfeited and there was no recourse. I would like to have my money that I'm owed. I should add that I have the same account number but a new card.
