Bain Property Agency

Where do i start? All complains lodged at start of tenancy. (I was asked to like it or lump it at 7 months and was asked to leave due to not paying rent after 7 and a half months), (paid rent for the first 5 months)
The roof was badly damaged and when it rained it would drip through the roof and into the loft, where basins had been placed (which were full) under the ⁵⁄₆ drips. One so drip would drip onto my bed through a crack in the roof. They repaired the roof 6 months later, as far as im aware the crack is still to be repaired.
Most of the windows were leaking or would let in a draft and if bad a whistling noise. (repaired after 6 months, the man fixing the windows said the windows were too old to be fixed and needed replaced as soon as).
No heating or hot water for duration of lease (breaking the water and wind-​tight guarantee).
They would come and let themselves in unannounced to ask why rent wasn’t paid stating they need the money before they can repair (they had 5 months of us paying full rent)
Washing machine broke down and took them 2 months to get a 2^nd hand one delivered to us, so we had to handwash or find other means (use friends and relatives).
Kitchen sink leaked as the u-​bend would not connect to the pipe.
Took them almost a month to fix a broken light.
Let themselves into bedrooms without asking the occupant on multiple occasions.
