that might have been the case with your friend but i just saw my neighbour 1 month notice to vacate and they endedup paying additional cheque for one monthe with the revised rent since his salary was paid via the bank and same is my situation

the one mistake i made is i signed the contract with this bugger thinking that my rents will to be increased next year i never knew the ren will go up after a year but strange that goverment dosent intreven and increase my notice period to 60 days intsead of 30 days
