They have no set day that they turn up. When they do turn up, they don't make their presence known until they are actually at the window. Today they turned up at 8.33am and caught me in the middle of BFing DD with my dressing gown wide open. I don't shut the curtains because you can't see in from the street (we have a front garden). This is about the 4th time they have caught me in varying states of undress. Once I was in the bath. Once I was inserting a maternity pad into my duds. Is it too much to ask that they just knock on the door first? I can't be expected to shut my curtains IN CASE the window cleaners come can I? They could come any time of day on any day of the week.
Plus we pay them a tenner each time - and they're rubbish. They have blatantly missed the kithen window. It's filthy.
