I experienced the most unsatisfactory delivery service. The designated delivery timeframe was 11 am to 12 pm, but the driver arrived around 3 pm, consuming our entire day. Subsequently, upon arrival, he refused to wait for 5 minutes, displaying impatience in front of the building, where elevator usage takes time. Threatening to return the groceries to Walmart, he began unloading them outside, claiming inadequate payment for carrying them upstairs. Additionally, he criticized the quantity of our order, disregarding the convenience we sought through the paid grocery delivery service. This experience contradicted the purpose of a smooth transaction, and I hope this review reaches both the relevant personnel and potential customers considering Walmart's grocery delivery service.
