3 tasks: 1. Fix the roller blind. The chain mechanism needs to be replaced but we cannot seem get the blind down from the wall to do this. We do not have the part to fix this. 2. Install TV bracket onto metal stud wall. We have the bracket and screws required for this, just needs install. We have marked the drill marks on the wall. 3. Reverse Hisense HR6BMFF453B fridge door. We would like this to open from the right rather than the left.
