hi,
i and my wife move to this studio on last 23rd of may and we signed a assured short hold tenancy agreement with the landloard.things were fine untill 10th of august. because our heating was shout down and therefore we didnt have hot water of heating for untill 7th of octomber.and 19 th of octomber our landloard sold the whole property to another person(now he is the landloard-he fix it on 7th octomber).and her send us a letter saying from now on he is the landloard. so we said to him about our problems(including not fire alarm for the whole the block-including another 5 studio flats) when our first meeting.But he said he gonna fix the things after he finished with the shop because he need to open the shop. so he didnt ask money for september and we didnt know who to pay or nothing.(and we coulnt move because we didnt know how to get back our 1 month holding deposit).
and on 7th octomber new landloard ask for the money for september and octomber.and we said we would like to pay full amout of 650 per month for octomber and we would like to have discount for the september becauae of the inconveneance.and we paid full amount for the august also.(cause in august we didnt have hot water for almost 3 weeks).so when i talk with landloard he told me you can offer a price for september and i said 400.couse after we came we fixed winddow and some stuufs cause without heating and brocken window make life unliveble.but he said he cant agree with that and you have to pay full amout and its not his responsability about the window because it has been brocken before.

so my question is should i pay full for september or how much i should pay.because we came here to live peacefully with order andwe just got married and we didnt have life at all apart from suffering with this problem.or should i do something with legel to this problem.
please if someone can help me as soon as possible we would be thankfull for ever.
