Hello @Boroughsitters and a very warm welcome to the Community Forum.
I am sorry to hear that you have not yet received a review for your recent sit, sometimes life in general can mean that they may have overlooked writing one for one reason or another or perhaps they are new to TrustedHousesitters and are unsure how to complete a review. Have you sent the ‘request a review’ option on your THS profile yet or have you tried sending them a WhatsApp to ask if they could complete your review for you and outlining the importance of this?
I have attached another thread you might also like to have a look at and I hope you will receive your review very soon. 
Also, for reference, as a member you can also add your TrustedHousesitters profile on to your Forum profile by following the attached link, should you wish. This will then enable others to offer you helpful advice and feedback.
Also, remember you can use the spyglass symbol at the top of the page next to the TrustedHousesitters logo and search for any questions that you may have as they have most likely already been answered on here and of course if not then please just ask!
