My son is in another state interning after his graduation from college. The company for which he is interning provides housing but not food. So to help him get started since, it's as if he's on his own setting up a home for the first time, my daughter and I found a grocery store that works with Instacart. We had close to $300 in groceries delivered to him through Instacart. Now giving credit where credit is due, the woman that brought the delivery to him was great. She texted him when she was close to his residence and made arrangements with him to be sure they would connect without a lot of trouble. Excellent service on her part. And she provided him with a receipt of the products delivered. Now the problem was that the receipt online and the actual receipt did not match. The online receipt was about $25.00 more than the actual receipt. I was charged a tip and a service fee AND WAS NOT refunded for the difference in the price. Am I wrong to demand a refund of the difference? I was expecting to pay more than the actual costs, but since it costs less, why should I not receive the difference returned? I sent an email informing Instacart of the discrepancy, with copies of both receipts Aliyah, who responded, replied in a very timely manner. We went back and forth several times and the same line was used repeatedly, "we can not refund you the difference." Why not?
