Illelagal electricity connections

Landstar are the renting agents for the block offlats next door to my house, the rent out 2 bedroom flats to families of 6 and more occupants.... ******* electricity connections running from the main cables across the street.... one of the tenants uses the parking to repair cars and install sound systems making window rattling noise all day and night... complaints to Mr Mike are ignored.. little has been done, on the positive side though... One if the rental agents, a young gentleman Claudio Barreiros has contacted me and is trying his best to sort out the problem..
