I tried Instacart for the first time as a convenient way to send my son the makings of a steak dinner for him and his roommates for his birthday, even included a birthday cake. The whole experience has been horrendous! The shopper claimed they were out of stock on the main ingredients even the cake at Kroger. I call [censored]. They even switched out the steaks for organic steaks, then claimed they were out of stock. They delivered corn and milk for my son's Birthday. When I called customer service they blamed me saying I clicked NO Substitutions which was a lie since the shopper substituted the steaks. Then I rated the service and the replies I received offered free shipping and credit towards an account I WILL NEVER use again. I was told a supervisor would call me to discuss the situation, which never happened!
