Can't deliver online purchases and make you follow up till you go crazy

Woolworths has been so unhelpful in addressing the non-delivery of items purchased online. They just accept that their useless couriers response of "incorrect delivery address", when the address is correct. When escalating via the contact email, you never receive a reply. When you call, they reconfirm your details and assure you that it will be escalated to the courier, which it never is. When you call and ask for the courier company (FedEX), they give you an incorrect tracking number that can't be found on FEDEX, despite reading the tracking number back to them 3 times to confirm it's correct. Called them again, demanding a date and time for delivery and won't drop the call until confirmation is received 20min+. It should not come to this from a reputable organization. Order number o***.
