Starbucks Coffe Mobile App Error

I recently changed my credit card, but I forgot to update it on the Starbucks mobile app. As a result, my Starbucks mobile account got blocked. I found out it takes a day to reactivate the account. My son, who goes to school near a Starbucks, relies on the app for purchases since he’s too young to carry cash. Because of this small "mobile error," we ended up with a 24-hour lockout and my son went hungry today. It's absurd to be inconvenienced like this in the 21st century. Such a trivial mistake causing such a big problem is unacceptable.
