@tomgirlbcGoolge maps allows you to down a map to be used offiline. For IOS it keeps it downloaded for 30 days. I used this when I was in Mexico, worked pretty well.
Same thing happened to me. The Walmart employee on fiday told me that I would recieve the $25 credit. He said it was no different than me activating at home. Now to figure out how to go to the moderator with the info.
