Regarding updates of apps

[Vikas804]

I was downloading an update for temple run 2 ,however due to slow speed of net broadband and 3 g both it is not downloading. Kindly tell me how to stop the update from downloading altogether and try some other time as due to the ongoing slow downloading I am not able to open temple run2. The message comes that not able to update. Cancel or retry. Even on selecting cancel it is not reverting to its original icon and appearing in downloading format.
