Discovery Miles outrage

I am outraged! I had the sum of R760 in Discovery Miles removed from my account because Discovery Card made a mistake in February 2019 and awarded too many miles to their customers. So, they just decided with no warning to remove these miles! But, because they felt bad they reimbursed their clients R100 in Discovery Miles just to make themselves feel better. Unbelievable! This is seriously making me reconsider all the business I give Discovery. Discovery are constantly shifting the goal posts and they think that their customers do not notice. Be warned!
