i've got 2 payment from surfpal..it's the daily payment, however i think the payment is too long to wait, always more than 24 hours. TOS said that the payment processing is 48 hours indeed, but i just feel that i'm wrong choosing daily payment's plan. The "paid on expiry" is absolutely better i think.
Here is the proof :


After my first upgrade expired, i'll re-invest with "paid on expiry" plan. :)
cheers..!
