Wuhu, destroyer of consumer trust

I am no marketing expert but when a brand promotional website like Wuhu breaks down customer trust and confidence by failing to deliver on promises, that is an inexcusable act. Since September I have been trying to redeem my accumulated Wuhu points for a R50 Checkers voucher but no such luck and Unilever Customer engagement are no closer to bringing this seemingly small matter to a conclusion. I can go to Checkers and buy a voucher. How can they claim to be out of stock, week after week? Other people are having similar difficulties. Social media is filled with complaints. Don't fall for the promises of cashback, Wuhu have no intention of fulfilling their part in the program. How Unilever allows this sham to be associated with itself says a lot about its business ethics I think.
