Useless Online Delivery - No deliveries

Useless online service, they don't deliver! Hifi-Corp should not sell online of theythe can't deliver. They sent an sms on the 1st for an item purchases in the 28th of August promising to deliver on the 3rd. Today it's 10 September and I still haven't received my delivery. Useless absolute nonsense how can an item go from being ready to deliver to sitting at their warehouse! I call them and I'm told to wait 24-48 hours before I receive feedback what ******* is that!
