I did a free trial of Instacart Express. Received an email 3 days before it ended to cancel it or I would be charged. I canceled it multiple times on the app and online but it still charged my card. I'm pissed off and had to contact instacart themselves as it's the only way you can disable / rid your account - info. Poor app not to mention my deliveries where always marked complete at the last minute but arrived way later (after the time frame they should've been delivered.)
