Stressful, time-consuming support and wrong prices in the store

my ability to make transactions was blocked, at some point I went to buy something and entered the CVV card incorrectly several times, now I want to take advantage of the Christmas promotions and I can’t because of the long and stressful support that doesn’t answer my questions and doubts. Another issue is that the prices in my store are astronomical compared to the prices they should be in my currency.
