Just now, went to singtel shop with my dad. Successfully transferred ownership. But cannot upgrade to 500 mbps plan, only can upgrade to 1Gbps or above plan. The CSO serving us checked, told us 500 mbps plan is no longer offered. 
Also asked to change from home analogue line to home digital line, was told there is a chargeable fee of $140 as already started the fibre bundle contract. I didn't agree and continue with the analogue line. If requested to change to home digital line when calling the hotline to do the migration, then it is free. Need their engineer to come to install home digital l line, cannot ownself install.
