You can upgrade your account at any time. It is free to upgrade, and the only charge you would be responsible for is the price difference between your current plan and the plan to which you'd like to upgrade.
For example, if you already paid R15.00 this month for your current plan at Ramkat, and the new plan is R40.00 per month, you would only pay the R25.00 difference. If you upgrade halfway through the month, we will charge a pro-rated amount, and the normal monthly fee will be charged next month.
