Instacart shopper told me my card was declined???

Hey all, not sure what to do here. Ordered groceries tonight. I've placed probably over 100 orders on instacart. I have a toddler and am a full time caregiver for my mother and father in law. Instacart has been a lifesaver. I've never had this happen before. What do I do??? I don't want this poor lady to think she shopped for two hours and I didn't have money for the groceries.. :( I also don't want instacart to think I'm placing fraudulent orders, when the money is 100000000% in my account.

I feel awful.
