Hi OzBargain,
Has there ever been a time where a system error for a service, subscription or product has cost you money? Obviously this comes down to being diligent with money. Obviously most of us are tight arses but not all of us are accountants so having the scrutiny to pick up on these things requires time and effort - if you're checking absolutely everything with a fine tooth comb.
For example, me and my partner recently signed a lease for a rental property and we were able to negotiate with the agency to make monthly payments even though it was listed as a weekly payment amount. After the first couple of rental invoices it appears as though the calculated monthly amount varied from the initial weekly amount by a total amount of $77 over the term of the lease(12 months). This was put down to being a "calculation of the system" according to the agent. He has yet to provide a valid explanation.
It's only obvious to me because we were expecting to pay a certain amount and the monthly invoice is higher. Had I not have been diligent I probably would not have noticed.
Another example might be the Centrelink debt letter scandal. Given that we rely so much on these systems, it appears one cannot be diligent enough these days with their moneys.
Discuss.
I think of it as a system error but it was probably my error.
