Deal or No Deal

I love this game have tried to find an app just for this game GSN appears to be the only one I like, when it works. I have lost millions of coins, some Ive even purchased.
There seems to be a bug when you get to Deal it blanks out, Ive bet up to 30,000. Accepted deals,blanked out. When I
Report Im told they are sorry they added chips, a generous 1000, which doesnt even equal my bet. Im told they cant compensate on potential winnings. How is it potential when the bank offers me xxxxx. And I accept and it blanks out????
And while Im on a roll, the daily bonus, last month I always land on 200-300 x 5, this for playing daily???
Not to mention Ive maxed out months ago, at 100 and can no longer level up. Thats a crock, anyone else have these issues. Know of a Deal or No Deal App, similar, without bugs.
