Hi, I have a receipt from my local swimming school that says my child's last paid lesson will be on the 19th of October, but their computer says the last paid lesson was the 12th of October. This is the 5th dispute I have had with them regarding the payment of fees (always the same thing, their computer is different to my receipts). The last time this happened, one of the receptionists actually changed my receipt to match their records. My question is, should they honor my receipts or not? If they don't honor the current receipt, what do I do under Australian Consumer Law? They have already made me pay for the lesson on the 19th of October again but there is doubt as to whether the manager will extend my payment by a week and honor my receipt. Thanks for the help!
