I have the same problem. They let you order and pay for the goods then dont keep up their end of the deal.
I ordered and paid for my items on 27th May 2014. Used the coupon sent to me in the mail too. I was promised delivery on 30th then I get mail stating they are having trouble sourcing my items. I replied with an angry email with no response. On the 29th I get a mail that the order has been dispatched for next day 30th. The next day no goods arrive but I receive another mail stating that goods will be arriving late -> 12th June 2014. I reply with an even angrier mail, no response from Kalahari. I so wanted to cancel the order but then you end up losing out as you cannot re-use that coupon
"and then i wrote an even angrier post on this site I found when I Googled 'Kalahari sucks and didn't deliver when they were supposed to'. I saw other people were also berating Kalahari's service."
