Still waiting for my refund

I have had the worst experience with twisp! In less than 6 months have had 2 batteries replaced and 2 USB chargers! On the 6th June my charger packed up drove all the way to canal wAlk to get a new one, get told by the kiosk they can't replace it (even though still under warranty) because I bought it from kalahari and need to pay cash! Paid it and got home the new one didn't work either! The following week I went to head office Tim replaced my charger that was still under warranty and will refund me for the 2nd charger I had to purchase cash! IM STILL WAITING I have sent numerous emails, get absolutely no response, I have made a few phone calls and always an apology and STILL NO MONEY! i find this absolutely appalling to treat your client like this for something that should have been replaced correctly from the start!
