Can I increase my credit limit?

Yes, you are free to increase your credit limit.

To increase your credit limit higher than the default of 3X of your monthly subscription, you would be required to pay a deposit equal to the increase requested. E.g to increase a $300 credit limit to $400, you would need to pay an additional $100 deposit.

NB: deposits are non-refundable while your account is active. Deposits are only refunded (full or partial) after the account has been closed and all outstanding balances have been paid.
