Discovery is a Dishonest company!!!

BEWARE of DISCOVERY VISA CREDIT CARDS. I recently went on a trip to the USA where I discovered to my horror that my Discovery credit card was declined when I swiped . I lost my car rental booking as they do not accept cash , which ended up costing me around R10 000 besides extreme frustration and desperation which one can not put a price on. They also declined my card when trying to get an Uber on the same day for 11$ . They really #@$ me up. This was despite me contacting them prior to leaving and the consultant telling me sometimes vendors swipe and sometimes they require a pin number. Needless to say they did not respond to my emails or phone calls . Discovery you are a dishonest company !!! You need to inform your clients the limitations on your products .
