At best, this agency is consistently rubbish and the woman mentioned in other reviews is tactless and rude, the most shocking is believing I'm not a British citizen "with a name like that".
As others have mentioned, they assume it is fine to give less than 24hr notice if any notice at all. A couple of occasions I've discovered that they've entered my home without my knowledge or permission and also have just shown up at the door expecting to be let in.
They are the reason why I didn't extend my tenancy. I much preferred paying the extra expense and stress of moving again than to deal with them for another potential year.
