Love the game but full of bugs

The game is full of bugs. I have completed the game 100% and unlocked all prizes -- new music, -car and retro mode. But these are the bugs
- every time I launch the game it has to show me that I complete all 3 bonus task
- it always tells me that I unlocked the India bonus track.
- since this last update the button to restore "purchased" game does not work!!! And the game is stuck in retro mode with the toggle missing.

Get some QA done and have it fixed Please!!!!
