While reading there t&c I found this nugget;
When reviewing Your withdrawal request, the Company reserves the right to allow You to withdraw monetary funds from Your Account in installments. The number of installments and the period of time when the funds will be fully released will be determined by the Company reasonably, on case by case basis and may vary depending on the payment channel used for the withdrawal.

Certain requests on withdrawals can take considerable amount of time to be processed and approved by the Company. The Company reserves a right to consider and approve any of such requests within reasonable period of time.
