Not sure if you bark at the right tree.

Think it this way, u go A**** mall, saw a S****** phone u like and buy it, after that u found it is used phone and u bark at S*******? S******* phone is being displayed (analogy to the Maybank promotion pamphlet that being displayed in TGV) in A**** mall but why u bark at S*******? The phone is sold by A***** (offer of priority lane by TGV in ur case) but S******* (MBB in ur case) is not liable to it.
