Im am trying to play genesis two and it says it requires the 32$ a month plan. I switched the plan 16$ a month plan to the 32$ a month in the basic menu but it didnt charge me money nor added the plan even though is says the 32$ a month plan on th basic tab What do I do?

The this service operates is like how most rental services operate. They pre-charge for your initial order, and if you alter your services any additioanl charges are added on the next month's bill as pro rata. So your $16 initial charge is for the server, any days you use the server at the $32 plan will show up on the next month's bill in addition to your charge for your subsequent month. That breaks down to just slightly more than $0.53 per day used.

This is a standard business practice for rental charges.
