Cannot Schedule Delivery time

I cannot schedule a grocoery delivery time on Wlamart Togo, everytime I try to it says all the days are full for the next 3 weeks. I called Walmart Togo Customer Service and they did not even know that there was a problem. I am so bummed, I love ordering from Walmart but I really need my groceries tomorrow so it looks like I will have to order from Safway...Bummer!!!!
