USA East maps disappeared

I don’t use Navigon any more even though I still have the USA West maps. I bought USA East maps in an “in-app promotion.” All was great until a major iOS update, the the East maps disappeared even though the app showed a listing. I contacted Navigon support and they asked me to explain via email to explain what happened which I did with a screen capture of the problem and then I never could get them to respond with a download solution. They said I would have to repurchase the East maps at full price. Worthless company IMO, and shocking that in this day and age to have a situation like this arise with no attempt to help a paying customer.
