Standard Chartered Bank Hong Kong — Messy work in home mortgage application

That SC bank branch repeatably missing to ask me the information which was necessary for the application of home loan/mortgage for my new purhcased flat. They asked me to return back to the branch couple of times to re-submit the document or signature as they simple missed out and misunderstood their interal procedure. It didn't not waste my time (as i am working overseas) and SC bank also failed to complete the date of the mortgage registration in the bank that making me lose some interest benefit in this loan program.

As a service provider, Standard Chartered Bank is not able to fulfill the commitment of Mortgage One service owing to its internal error in procedure. They should be liable to this fault but they didn't.

And, the staff who handled this was lack of sense of customer-orient and keep making me nervous and anxious.
