7 per cent increase is the most concerning thing about this thread. Surely not. Mine is up for renewal in 6 weeks time.
Cheap and liar landlord sums up about 80 percent of HK (with apologies to any decent ones amongst us here)
I would say, if the amount is not too big, suck it up and live and learn.. If Landlord is a real scumbag (more likely), nothing much you can do about it.. Also don't forget you are in first year of contract so he can trouble you more if you choose to go legal way..
Just get the 7% back when you move out by not paying the last rent (s) and make the last payment 7% less.
If you have WhatsApp logs showing the original ‘verbal’ agreement then you’ll be fine.
I would however Write a couple more WhatsApp’s to him, detailing why he owes you 7% and including also the issues with the damage that he’s refusing to fix. And make sure you keep those WhatsApp logs in a separate file on your computer so you don’t lose them
Sage suggested and keep all whatsapp log, message him 2 months before expiry of contract and tell him you don't trust him based on previous experience so not going to pay for last 2 months (supported by Whatsapp log), see how it goes from there.. If you still want to claim 7% as well, you may have to do it 3 months earlier and pay 7% less and so on..
Don't take it the wrong way, but the way you describe your situation is convoluted and difficult to understand. So perhaps your landlord misunderstood, too. Also, your own fault for being too trusting and not putting it on paper.
Having said that, LL needs to fix the water leakage and the door ( what ever the problem is).
So send him a written message he has to fix these and give him a deadline. and put in writing that until it is fixed he is responsible to any damage to your property arising from the water leaking, and health risks due to mould and you will seek financial compensation . Also, put in writing that landlord will be responsible for any financial claim for any injury the door causes to you or anyone on your property, e.g. outside workmen etc.
