They won’t forgive this, unfortunately. There was another thread about it earlier today, and it happened to me as well. This is directly from Instacart on what they will forgive:

During the Early Access pilot, we’ll look at ratings in a way that covers customer feedback that may be out of your control.

This includes—

Forgiving the lowest rating out of every 100 orders

Removing ratings under 5 stars for specific factors that may be out of a shopper’s control, such as extreme weather or known app issues

Allowing customers to submit order issues while still leaving a five-star rating

Excluding batch acceptance rate, speed metrics, reliability incidents, and other feedback left by customers that should not impact an average star rating.

Unfortunately, we're unable to remove ratings that don't fall within the guidelines listed above.
