When do the funds available in my bundll wallet replenish?

When bundlls are repaid, whatever the amount was that you repaid will be added back on to your bundll limit as soon as payment is received. Remember, if you convert a bundll to a superbundll the value of that bundll will also be added back to your bundll limit. Any superbundll repayments will be applied back to your superbundll limit.
