The validity period of each tariff plan is 30 days. You can spend the entire limit in 1 day or stretch it for the whole 30 days. After 30 days, your remaining limit will expire. You can renew your plan, in which case you will again have access to your full request limit. Unused credits are not carried over to the next month when you extend the tariff.
You can withdraw funds from the system within the first 24 hours after purchasing the tariff plan. In this case unused credits will be converted to your personal account balance and you will be able to request a withdrawal through the ticket system. In the future you can also cancel your tariff, but the funds will remain on your personal account balance for purchasing other products and/or services within our system. Withdrawal from the system after 24 hours is not available.
