Poor Customer Service @Clicks Pinecrest Mall

I am very angry at Clicks ‘ I had a cash back that I needed to use and they told me a rude answer tht I can’t use it because their till are not working and in a rude manner even the learner was soo rude ‘ I had to fight and be delayed while my child was pressed nd needed to go to the loo....I would never recommend Clicks Pinetown to anyone !!!!!! Am extremely angry
