Instacart gives customers 3 days to decide if they want to erase their tip which 90% of customers do just because they can and there is no penalty until you do it 10 times in a row because they only care about the customer and look at their shoppers as more than disposable. You can only contact shopper service over direct messages which makes no sense because customers can reach customer service within 2 minutes on the phone. The worst business model of any of the phone job apps. Stay away.
