ChrisP. said: I have exactly this problem with 30 day old duplicate transactions showing up on my Alliant Credit Union credit card account. Some things to note: 1) I have called Quicken tech support and explained the problem in great detail. They were unable to fix it. They were also not interested in contacting Alliant themselves to investigate the problem. They said they would need more users with the same problem reporting it before they could take any action. Clearly there are users with the same problem. [Removed - Speculation] [Removed - Off Topic] 3) Everyone that has an Alliant Credit Union credit card account will have a savings account as well. That's the way Alliant works. I bet those of you with an Alliant credit card have created Quicken accounts for at least one other Alliant account. As an experiment I tried disabling online downloads for ALL Alliant accounts (I have a checking account as well). This did actually seem to temporarily fix (or at least reset) the problem. I have a feeling if you only disable online updates for one of the accounts, and the entries for the other accounts remain, then some element relating to the problem is preserved. So, definitely try disabling all Alliant accounts, and then re-enabling them. But, it's not a permanent fix as the problem came back. 4) It's very frustrating that I can't get corporate Quicken to talk to corporate Alliant. Likewise, I have asked multiple times for a call from Alliant from someone tech savvy (not regular customer service), and I get promised a call. Alliant never calls back. [Removed - Off Topic]
