This payment will be made quarterly. In terms on when you get paid the reward, I hear it's from the 15th January onwards. So if your January bill is before the 15th, it will be added on your February bill, and then once a quarter from then on!
It will be on a pro rata basis from the date you switched till the end of that quarter. So if you joined in December, you'd only get one month's worth of the reward in your Jan/Feb bill!
