To begin with, I used a 15% discount in my first order that was redeemed as just “10%”. Then, for my birthday I was given a 20% discount that wasn’t deducted from my second order. After making a formal complaint the customer service is unable to refund any money. If you order from this website, bear in mind that their discounts won’t work and they won’t refund you any money even if you’re entitled to it.
