Does anyone else get double charged for groceries from a delivery service?

I get a double charge when a price gets updated from a grocery delivery service. It has happened more than once with same company.

Credit card provider says that they can’t do anything.

Delivery service says that it will be reversed in 3 or so days.

Is that normal? I payed ~$100 a year for service. I would prefer to be fixed as the service is valuable.
