Poor service

The staff from Twisp at both the Clearwater Mall and Cresta Mall shops are unfriendly and the customer service is pathetic. I purchased a Twisp at Clearwater mall and both the battery and charger was faulty. After a lengthy argument with the Twist representative I managed to get the faulty products replaced. Further I was informed that Twisp have a loyalty programme where I qualify for a free liquid for every 7 I purchase. I purchased more than 15 of these liquids and I still did not manage to get a free unit. Each time I query he Twisp staff members have a different excuse and they make Twisp's poor customer service my problem to solve. First excuse was that the Twisp staff members did not allocate the transaction details correctly in the system, thus the loyalty point cannot be allocated to me. Second excuse was that the system was off-line and loyalty points cannot be allocated. The third excuse was that I did not accept the t&c's of the loyalty programme (which I was never informed about at purchase and I never received a SMS from Twisp). To date I have not received any assistance / resolution from the Twisp representatives, and each time I query I get a bad attitude.
