Incorrect Opal charges

Does anyone else struggle with incorrect Opal charges? I love the convenience of contactless payments, but I’ve noticed a lot of discrepancies in how they are processed. We keep a very close eye on our bank statements and match them up to the Transport Connect Activity Statements, and it’s often very messy. Charges can be bunched up and processed days (sometimes longer!) after actual travel, which can make it hard to spot issues. I’ve just spent 20 minutes comparing my November activity (which is correct) to the actual charges on my credit card, and they’ve double-charged me for 4 trips ($10.88 in total). I’ve lodged a ticket, but I can’t help think how many other people might be affected who aren’t as fastidious as I am in checking this shit.
