Thanks guys for the info! I called PCCW and they had the nerve to tell me that they will refund the installation fee ($475) over a 18month period (when HGC and Wharf offer free installation). I guess people still fall for these marketing ploys.
Instead using one service provider (fix line, broadband, and CableTV), I'm going to end up with 3 different ones (Wharf T&T, i-Cable, HK Broadbandnet respectively) because they offer the best deals (in order to take shares away from the entrenched).
I'm glad I've done my homework before being trap into any long term agreement.
