We too had the worst experience with this agency. They provided a nanny/housekeeper who was not fit for the job. To be honest she wouldn't have been fit for babysitting or washing dishes even and I think her CV was a total fabrication. They refused to put us in touch with her referees when I wanted to check on her as she clearly was out of her depth. She couldn't cook, not even for a 3 year old! Not even beans on toast. She left our daughter alone in the bath, she lost her on several occasions, she couldn't do any housework whatsoever - she couldn't wash up a dish or even use the dishwasher (Despite being almost 30!!). The agency were no help at all and wanted to charge us another £3000 to find someone new!! Absolutely no way I would trust these shysters with my child ever again. Stay away. You'd be safer on gumtree!!
