Bravo Supermarkets

On 8/20/19 12pm I purchase the lala yogurt pack since it was on sale $3.99 and I love this yogurt, I go today to open one and it smells and taste sour. Expiration date on it says 9/14/19. I have pictures of my receipt, pictures of the yogurt I purchased and pictures of how spoiled it looks. I have worked in the food industry over 9 years and this to me looks like it was kept out and then put on shelves to resale and discounted. This was purchased at your 24-1834th Avenue long island city bravo supermarket location. I'm currently feeling sick because of this. Please have them take this serious and check all dairy products and to follow keeping food at a safe temperature, thank you.
