Late delivery, delivery of damaged goods

I first ordered a item from kalahari, they delivered it on time to me, I opened it the next day to find that it was damaged and didn't work... I requested a return of the item, I waited till the date they said it would be picked up, and when the day came I logged in to find that the pick up had been cancelled by kalahari... I phoned to query and they said they were sorry, and they gave me a refund and sent collectors the next day. Since I got a refund, I ordered another make of the item. The item was not released yet, it was released on the 31st of March, I ordered at about the 26th of March, after he release I was told that it would take till the 6th to deliver. It is now apparently with the courier company and has been for 4 days so far and I've heard no word of where it is. It's now the 7th of April and I still haven't gotten a notification that it's being delivered to me. Kalahari need to sort their delivery problems out or I'll just stop buying and use other online services of purchase. Order number is ***
