HORRIBLE SERVICE - DON'T USE THIS COMPANY

My address was changed to KZN even when I chose Western Cape and included a postal code. I don't even understand how a mistake like this happens when we include the POSTAL CODE - isn't that a unique identifier of areas? I noticed on time and politely called this company to correct the address. The following week my items were sent to KZN. When I called to find out what happened I was told that yes my address was corrected on the system but the person who made the changes did not inform management (this procedure doesn't even make sense). I keep tracking and there's no movement at all. This delay has already ruined one birthday and right now I'm nervous about another upcoming birthday since there's absolutely no movement at all on my delivery. I will never use this company again and I'm not the only one I know who has experienced this type of horrible service - a family member of mine experienced the same thing with someone changing the address and she had to drive to the delivery guy's place to fetch the item. Calling doesn't help either - I've called 3 times already and there's still nothing happening. What's wrong with your system? Why are you a delivery company when you get area codes wrong? A different province - seriously? Then silence from the company - not even a courtesy message to say "sorry for the delay, we made an oopsie and we're doing our best to get your package delivered asap". Just crickets.
