Fist time buying but def the last!

I Purchased an Ipad on the 16th of March on line, directly after purchased was made I realised that it was the incorrect item. I directly called Kalahari after purchase was made to cancelled and requested a full refund. I wanted to buy the correct item. The call centre agent informed me that it would be done immediately and that the funds would be reversed to my account...... Well, today is the 4th of April and I have not received a cent! I called once again this morning just to hear the same old story, \the unit was dispatched and we are awaiting the return of it"? What the HELL? I called with in 5 min after purchase and still the item was dispatched? And to top it off I am told to wait for the return of the item which I have never received before I can get my funds returned? [URL Removed] this is pathetic service!!!! I am a first time buyer but trust me NEVER again! I want my money returned immediately! But with your lack of competency I can assume that it will only happen next month!"""
