Dis-Chem Jean Avenue (Crossing): Extremely poor customer service!

Dis-Chem Jean Crossing doesn't care to help customers and ***** their money. Their online store doesn't work properly. Their promotions on the online stores shows incorrectly so you are forced to buy more products and supposed to get 1 free but when you collect your order you only receive the products you've ordered and no free products. They claim that the promotion is wrong on the online store but they don't refund you and they don't give you the extra free product either due to their system being incorrect, they don't even try to sort the problem out or help the customer. Their prices on the online store is also not correct and the stock levels as well. They don't contact you to tell you the product you've order is out of stock, they just replace it with something else like they want to and then the price is also less than the product you've ordered but they don't refund you either for this. This store's customer service is definitely unacceptable and extremely poor!
