Question here.
1) can the JMB really barred my access card which I'm only the tenant not the owner of the house. ( they barred the access card is to create problem to the owner but in my case here, the owner will not get any troublesome on it )

YES OFCOURSE.. Currently JMB is having issue with the owner and why he need to care about the tenant.. janji he can done his job then ok..

2) is it really legal where they barred my access card ? ( going to discuss with my lawyer in further )

Yes it legal, As owner didnt pay up for the fees.. it called bad debt.. and owner only own the unit.. not the whole unit/lift


3) for the condo I renting, we need to touch the access card to go the our floor, I heard the guard say the JMB asking the guard not to touch for us, hence ask us to use staircase to our floor. ( gosh, I'm staying 17 floor !! )

Maybe the only solution u can try is go meet with JMB and on the spot u call the owner let them talk about it
