I have 3 credit card accts with Citibank, and I had an old one that I discontinued in 2015. Around the first of this year Citi said they had a new download system and needed to reconnect. The first account they reconnected had all of its transactions since I opened it last April moved into the discontinued account as new entries, losing all the add'l info (account, etc.), four transactions that belonged there, and one transaction that should have gone into one of my other Citi cards. I didn't try to reconnect my other Citi accounts for 2 weeks, and then did so gingerly after backing up carefully, one at a time. They are ok. So, I tried downloading the messed-up account, and it sent all new transactions into the old, discontinued card account.
What can I do? (Note: I have been using Quicken for Windows for over 20 years)
