Twisp does not honour their warranty

On 15th May 2015 Twisp at Clearwater Mall replaced my batteries because the first set were faulty - that is now less than 2 months ago! Initially these batteries lasted a full day on a charge. Gradually they have deteriorated to the extent where they last only about 3 hours. A lady at the Kiosk tested the batteries and charger in the time it took me to have a quick breakfast at the Wimpy opposite the stall. She claims that batteries and charger are all functioning 100% and simply refused to honour their 6 month warranty. How she can conclusively state that after such a short test id beyond my comprehension.<br> <br> I find this service from Twisp complete and utterly unacceptable. I think a) that they should put their money where their mouth is and honour the warranty and b) that new batteries should be delivered to my residence. Alternatively they can refund me fully for my purchase (+-R1000).
