Survey incentive ****!

Very disappointed in Hippo. They asked me to take part in a survey with an incentive after using their services while searching for new car insurance. It took over a month for the incentive, a R500 Pick n Pay voucher, to be sent via email. I tried using the voucher at my local Pick n Pay, they did not know what to do with it. They then escalated the issue to their regional manager who was not aware of any partnership with Hippo. They later escalated to their highest office and the response was that they are not fami**** with the partnership. Why send people unverified incentives? It's such a waste of time to ask people to take part in your surveys then get humiliated and disappointed when they try to redeem them. I would like my promised voucher....one that actually works!!!
