I believe he purchased per channel @RM40/month and not as per pack @RM30/month that definitely will be tied for a year contract 

The term all the sport channels could be subjective to some, mostly soccer and but for BPL hypptv still rely on Astro on selective matches. Yup, RM30/month promotional price, else RM50/month.

TM never forced me to take any premium pack during my STB collection, just doing their promotion as usual but I resisted. I said to them that I'll only decide if I am satisfied with all the channels during the trial 30 day period.

To my understanding wajib applied to those 4mbps whose intended to take hyppTV into their monthly subscription, any premium packs will do.  But for 8mbps, they entitled to 17 free channels but premium packs is just an option, I am the one who walk out carrying my STB without obligation to subscribe to any pack. 

Don't do via online, go to TM point yourself and signed it from there 

ok, I've no idea if that is their procedure now, but buying any single channel wouldn't hurt you much as the subscription is valid only for a month and no contractual for that, except any premium pack at 12 month contract. But opt for Jaya Max would be a good idea if you love to watch the classical Tamil movies in greycolor
