Sorry, what is VI and PP again??
I am currently with DBS Treasures and also Citigold, and had pretty bad experience with SCB. Basically I think what your experience is like will just boils down to one thing: the RM himself/herself, how much s/he values you. Of course there is probably a whole set of algorithm guidelines behind them to assess our credit worthiness, assets, occupational potential, investment knowledge, etc etc but its still up that particular RM in-charge of you.
I have RMs who basically booked free car rides, airport lounges (even when I am not entitled to), waived off late payment fees / finance charges, give me free tickets / gifts because I was probably very valuable to them, or they are new and do not have enough clientele. At the same time I also known RMs who don't even bother to reply my email when I inquired about a product, maybe think I asking so many times never buy.
So now that I have HWZ to seek more advice on investments as well as reading up on my own, these RMs become just runners for me. In that case, I would always choose new birds instead of those Hermes / Chanel-clad high flying RMs, because the latter would just have their nose in the air when they realised you are not going to give them that 3-5% sale charge for yet another silly mutual funds.
