Hello, for some code you have to wait few hours (to get them by mail).
Enter the codes obtained here https://wrobot.eu/allopass/
You can check the available credit on your account here : https://wrobot.eu/clients/credit/
To obtain the code quickly the best way is to call. But, I don't have any information about the payments or the status of the payments. I get information and money only when you use a code (these codes can be used on several sites, that's why I don't get any information before a code validated on this site).
