Does any mummies have reviews on pem confinement agency or other confinement agency?

My cousin took PEM and was satisfied with the nanny's service as well. However, as it is an agency, there are bound to be hits and misses as I have also read about lousy nannies from PEM which had to be sent back. It's not so much the agency as the nanny herself. For PEM, they had add-on postnatal massage and confinement herbs package so you don't have to book separately.
