Корейская косметика ISEI (Кривой Рог)

They sent an SMS to Viber indicating the discount - 35%. Arriving at this store, choosing the product, I said that I received a discount, to which the seller replied: "This discount has ended on June 29." I say that I received SMS exactly today. She asked my phone number and after checking again she said: "no, there is nothing discount on your number!". I paid for my order with a card. And all the same, she decided to ask the seller for the third time: rumor, SMS has arrived today, here it says DISCOUNT. To which they answered me: "so why didn’t you say this before? It was necessary to name the promotional code, you paid through the terminal and now I can’t do anything!". And I didn’t say much, say 3 times to the seller, is this not considered anymore? Honestly, there seems to be nothing of the sort, but the sediment has remained very unpleasant, and more than that, I basically didn’t leave a foot in this store !!! Although she was a regular customer.
