A Purplebricks spokesperson has confirmed that it is no longer possible for members of the public to post reviews via Facebook.
The facility was disabled on Christmas Day, making it impossible to view or leave reviews.
Instead, Trustpilot reviews can now be seen on the Purplebricks Facebook page.
A Purplebricks spokesperson said: “We welcome genuine customer feedback, as is evident by over 11,000 audited reviews on Trustpilot, with an average score of 9.4 out of ten (rating excellent).
“However, we have turned off our Facebook review functionality following clear cases of misuse, the inability to limit such reviews to genuine customers and the fact that our Trustpilot reviews can now be accessed direct through the Facebook page.
“Feedback from our customers is actively encouraged at Purplebricks, good or bad, and we will always listen to it, improve and make amends where necessary.”
