Bad customer experience

In Upington our cashbuild store is for the past year very dark in the store.When complaining to the manager he sarcastically ask if I should use his phone for lightning.Is ashamed that a company as cashbuild allowed their customers to shop in the dark.We can't see anything and had to use our phone light to view their products.Its quit clear that they don't care about their customers or is it maybe where the shop is located?
