Terrible service at KFC Grayston

The cashier at KFC grayston drive debited my account twice for the same transaction and this is not the first time. The manager, Thenjiwe, at the store was very unhelpful and said I should bring a bank statement so that they can return my money. Now I am forced to go around looking for statements just so I can get money back. Definitely the last time I will be spending my money there
