my fren called to unifi cs to ask if he does not wan the hypptv, can he get some discount, the cs told him the discount only valid if he upgrade to vip10 or vip20 ...

Unfortunately, VIP5/10/20 is bundled with HyppTV & you cannot unbundled it. This is the reason why Maxis Fibre subscription price is lower as it does not bundle any IPTV service (on Maxis you can have Astro IPTV with standard Astro subscription rate if you choose to)

That is why I am staying on with TM UniFi 
In fact I was offered an upgrade from VIP5 to VIP10 with RM30 discount (hence only RM169/month, this offer no longer available) but contract renewed for another 24 months, discount is valid even after contract. And I accepted this upgrade.

I have heard much horror stories with Maxis Fibre like what you mentioned above, and to add to what you said, there have been so much complaints of poor customer service as well.

As I am myself also a Maxis Mobile subscriber (voice & mobile data), I have been getting call from Maxis sales team to take up their fibre service more than 3 times, even when I said I am still on UniFi contract, they still try their way to convince me that the RM500 penalty I have to pay can be offset with their price savings! (Marketing gimmick in fact) 

Oh btw, while many think that the HyppTV service is useless to them, well, it suits me anyway. I don't really watch TV often, but when I do, watching the free HyppTV channels (well, not really free, it's included in the monthly subscription fee anyway) is good enough - not to mention crystal clear video display from our 6 free to air channels.
