Well, I posted what I got to know from TD exec. I asked him the same thing thrice to be very sure! May be their execs are also not trained for new rules.
Btw, one more thing, they will refund the annual plan charges considering 11 months when calculating daily price. I.e. they will calculate daily price as plan price/11monthsx30days. And not 12 months. As per him this is because the annual plans are 11 month + 1 month free. I asked him to show terms and conditions page and he couldnt. Their platinum hd annual page says at the bottom, annual =365 days and not 11m + 1m free.
