Horrible customer service. Would NEVER recommend them!

Horrible customer experience. My clicks partner benefit shows activated on the profile but I have NEVER received any cashbacks. I had to call and ask for this and Discovery has been sending me from post to pillar for months on end. A few weeks ago they said they would send me a voucher, I still have not received any further correspondence or update. They told me to keep using Clicks and they will do a backdate and give me my miles - still nothing. Very disappointed in them and would NEVER recommend them to anyone. If I could rate them less than 1 star I would. Absolutely appalled.
