Is it possible to change the service parameters or accounting period at any time?

Yes, you can Change your order in the Order Summary. You’ll also find the option to change the billing period there.The system will account the original order, create a new order, and deduct the unused part of the original order from the new order. The ability to change service parameters or billing period can not be used 14 days before the end of the billing period. In this case, you must first pay for your original order and, preferably the same day, change your order. Then you will not lose one day without a discount on the billing period.
