I heard that tm no longer provide stb to new customer. What happens if my old 1 fail? I m forced to use apps for unifitv?

need to pay extra monthly charges? on top of the playtv subscribe plan?

Hello ...
yes .. I am having a old old set of hypptv decoder .. which is still currently in good    condition ...(using)

last few days ... I bought a second hand unit of decoder huawei  white ... trying to connect it  but screen show services unavailable ... even thought with ID and Pin ....

so called the care center ... and was told cannot unbind the mac address ..
so .. i show them picture of this second hand unit mac address .. but still cannot be "bind " .. and was advise that ..need technician to attend to my case but need to charge ringgit 53. for this services or ... else buy a new unit from TM  ..which will cost about 300 over ringgit .... or .. sign up for 2 years contract .. ( which i was recently turboed )  in this case the new unit of Hypptv will be free .. ..

I further argued over the fact .. that i am a good customers of unifi .. with good payment since the days of 1515 ....

they replied that the unit of old hypptv decoder is already expired with warranty /// and there is noting much they can do ... !!! is this true / ???

please advise me what to do next ... ?? 
thank you .
