My card was charged a $149.00 yearly service fee completely out of the blue, with no prior notice of any kind. Fortunately dealing with customer service was OK, and they said they would reverse the charge.
The next morning I see my card was charged $14.99 from Instacart before the refund they've supposedly issued has hit my account. I can't even remove my payment information on the site to avoid being charged more because of this.
Not to mention, the service was sub-par half the time anyways.
