Gigantic point amount on rewards card - what are potential consequences?
Of course, as a 'good' person (or maybe a 'stupid' person), I should call them, (wait 30 minutes in the queue), and then try to explain the issue to the service desk. I actually did that, and the guy thought I am nuts to even call, and told me to 'just use them they are yours now'. I don't feel like calling again and again until I get someone that believes it, just to return them their points. Calling generally does not solve this problem. You would need to write a letter using certified mail and send some reminders. Hopefully they should notice it, if not you at least have evidence that you have communicated. I could just toss the card and forget about it. However, I had quite some points on it that really belong to me, so that feels like I pay for their fault. There is no need. You can continue to use the card as usual. Use them and play stupid. This is not a good idea. They are clearly not yours. Somewhere in Terms and Conditions you will find some fine print about notifying Bank/Financial Institution about the errors. Best course, after intimating informing them via letters, keep using your card as normal and use your points as normal. You would roughly know your points balance.
