Awful customer service !!! Went to the counter wit...

Awful customer service !!! Went to the counter with $298 worth of clothes and told if I spent more than $300 I would get $75 off. Found a hat. She rings through $40 hat at the same time as telling me I only get $30 off because the hat is by the ring brand. By this time she s put the total amount through on my card. I look at the receipt and there is zero discount applied. I ask what s happened and she s says oh dear. Let me refund that and put it through again. Fail and it s a debit card and now I can t spend any money until the refund has gone through in a few days time. Short story is that I leave with nothing waiting for refunds to clear on my card and lots of people called managers in black jackets telling me it s happened to them before and there s nothing they can do. Absolutely terrible experience and no effort to have me leave satisfied. Online retail is the future without useless shop assistants!!!!
