15-10 games, no more seconds added after moves !


I'm playing always 15-10 games. 


Time was not added during the game, I was not disconnected and then even I played fast 1s per move (I should be credited of 10s) I lost on time!! ???


Another problem is that since yesterday my clock during games is always going down on screen. I need to refresh my game to see the correct time! But if I don't do that clock is decrementing to .... finally 0 !!!! and then I lost the game! 


Then, the only way to fix it is to consider I have never extra 10s and finally I'm playing a game within 15 minutes only !!!! 


It's a true fuc.... bug! :-)


Please help. 

Kind regards,
