I have been fighting with auspost literally for years. Finally just submitted a complaint to the ombudsman, sent the reference number to AusPost and my issue was miraculously fixed and I received two different apologies.
yup, that's ours. Oh we can't access teh driveway oh there's too much traffic oh it's an oh&s issue. yeah when your own staff deliver shit on top of other vendors, it's just one guy, that's a pile of horseshit. Final straw was them demanding proof my driveway is safe to access. Based on an 8 month old comment by one driver. Ombudsman can deal with them.
