No answer after dogs get sick

I’ve sent an email to the customer service explaing that I gave my English Bulldog the Hill’s medium breed puppy food. She ate it for 9 months and the yorkie would also have some of it. Once I opened a new bag both of the dogs got sick and started vomiting, they were sick for a week and didn’t want to eat anything. I thought it was a bug and gave it to them again but they started vomiting again. I spoke to a friend that gave the same food to her French bulldog, she also bought a new bag at another store and he also got sick, he ended up at the Bryanston hospital. Customer service responded with “Please advise if you have been assisted by one of our Consultants yet?“ after I’ve rep**** I didn’t hear anything from them. Thumbs up for making our dogs sick and vanish into thin air if we complain!
