What to do with management company of my block of flats suddenly putting all binson a platform near my window?

I have been away for a week - I have got back to my flat to find that the management company (at least I think that is who it is) has build a two foor concrete platform about 7 foot from my windows (I am a ground floor flat) with a ramp and they have now told all residents to keep their bins there! I am so angry, there was no consultation - I did not even know they were doing this. The view will now be of bins. The smell is horrific and there will be a vermin problem right near my flat - how can I keep my windows open witha small baby? Living near a bin shelter is also going to affect the value of my flat. Is there anything I can do about this other then phoning/writing to complain when they will probably ignore me
