Well, IB replied again to me, and this time their version of what happened is that I was only charged once for all the data feeds, and the reports I was seeing where it was showing me paying twice - were the result of a “display error”. Not sure how a transaction-by-transaction log could have previously had erroneous deductions over the period of a year, which were all somehow mysteriously removed, and in the end have the same cash balance as before though.... whatever, it’s like 50 bucks. I’ll just keep a close eye on the reports more frequently from now on I guess.
