Pessima experience at Ponto FRIO DE IPANEMA! I went in search of a blender, so the most affordable was priced at R $ 39.90 I opted for it, if at the time of closing the sale it jumped to 10, 00 reais more ... I avoided getting confused and accepted, after all it was only 10, 00
When it was time to pay simply THE CAIXA OPERATOR WAS AT LUNCH TIME AND NONE OF THE 10 STORE EMPLOYEES COULD RENDER ... And I wanted me to pay by card.
What do you mean, now I no longer have free will if I choose how I want to pay ???
Confused system, several employees in the salon with no attitude of helping ...
Poor quality!
I won't be back there again ..
