No you don't need the ladies permission to post a review, or to comment on an existing thread, including using their service providing name. Importantly you must never divulge anything which would positively identify a service provider, so never use details which they don't actively provide in their adverts - so no real names, specific addresses etc.
If you've been following the reviews for a couple of months you'll have seen that most reviews are deliberately anonymous which encourages honest reviews of services provided, good or bad, with no come back to any of us
With that in mind it's always a good idea to avoid specific details which could positively identify you to a service provider, e.g. avoid mentioning actual dates, or anything unusual which happened
Very few get it 100% right first time out, so accept any comments and suggestions on ways to improve future contributions, particularly from those with a high number of reviews/posts
