spent $68 and it doesnt work at all

I got the trial 1 month version for 99 cents and it worked fine. Then when I bought the in-app maps and traffic eupdates for $59.99 + tax it wont download but the app took the $67.79 out of my iTunes store credit so I paid for it and dont have it. I have emialed apple and BringGo and no one has responded and that was on Sept 11th; I purcahsed the app on Sept 10th at 1131pm and have tried several times and it keeps saying I need to download it and hit ok so I do that and it says problem with apple server..yeah right!!
