A Walmart customer says a grocery delivery that never reached his home turned into a days-long dispute over a refund. Other Walmart customers report both delays and quick refundsGrayson’s post prompted other Walmart customers to describe their own experiences with missing or misdelivered orders. Other customers on Grayson’s Facebook post said delivery problems led them to cancel Walmart+ or stop using Walmart’s delivery service. Grayson’s reported 20-day investigation period reflects what Walmart customer service told him, not a companywide policy. If customers still cannot locate their orders, Walmart asks them to contact customer service through its chat.
