I just called and as mentioned above there are 2 options.

1. Upgrade to 10M + HyppTV pack either a)platinum, b)ruby or c)Sport, pay only RM199 (RM30 discount)
2. Upgrade to 10M only with RM20 discount.

However there is a condition that I cannot accept here. If you are already is a 5M + Platinum subcriber(RM149+RM30). You cannot terminate the Platinum 1 year contract. This means you are not allow to upgrade to option 1 (10M + platinum) and pay RM199. You much upgrade to 10M + either Ruby or Sport + you current existing Platinum package, this end up to RM199+RM30. I find this is very stupid where TM is not able to terminate the Platinum contract and allow the customer to upgrade to 10M+Platinum where you can get additional RM20 revenue. It does not make sense to me to pay extra Ruby or Sport if I do not need it.
So I will not take up the promotion.

Thanks for the advice, I might want to do that after reconsider your suggestion.

I am in the same situation as you where my Platinum 1 year contract end march 2013 and now continue paying RM30/month for it. I do not know whether is the contract continue for another year. I forgot to ask during the call whether I can terminate the current Platinum and later subscribe again through the speed upgrade. Maybe you can ask and let us know.
