Misrepresentation of information and bad customer service

A warning to all woolies clients, I advise you to verify info on your slip as the assumption that there system is correct is inaccurate.

As you all are aware that woolies is currently running there promotion that if you purchase certain items you would receive 20% discount but if u were paying with a store card u would receive an extra5% off. This was not case when we purchased our items yesterday... only the 20% was given and the store card discount was not. As I’m sure we all aware of the Christmas rush and the queues that we have to endure to purchase items. We went to tygervalley yesterday after spending nearly a half an hr in the line to purchase said items. The manager advises me to return to the back of the line so that the discount can be addressed, as I queried the error. But had I not just stood in that queue to purchase items in the first place I would have understood. But to disregard my time and efforts to rectify your system issues is beyond me. Instead of the manager just opening an close till that was not being used, I must must accept there incompetence and waste my time further.
