Why does the deposit not work? 

Unfortunately, you have reached your weekly/monthly/daily deposit limit. After this has been reached, you will unfortunately not be able to continue playing. You can now either wait until the limit is no longer active or increase the limit. Please note that the increase of a limit will take effect only after 24 hours. 

Please try the deposit again in 15 minutes. If it still does not work, please send a mail to support@goldengrand.ch.
