@ElBWray very sorry to hear about your experience it sounds like a terrible situation to be put in . It must be very distressing to take care of a pet that is in pain. I note that you say that you already contacted TrustedHouse Sitters about this situation. What advice and support have member services given you thus far ?
It is against the T&Cs for a homeowner to deliberately conceal information about the poor health of a pet . The listing and Welcome Guide must be accurate.
Removing a review isn’t something that THS will do routinely. However if you raise a dispute because of the inaccuracy of the listing that didn’t disclose the poor health of the pet and any other serious breaches of the T&Cs - they will investigate and can remove the review.
Did member services explain the complaint / dispute process when you contacted them ?
If you have evidence that the homeowners did not provided an accurate listing and welcome guide you can raise a dispute. Include the original listing and any other information you have ( photos , screenshots of text messages between you and the homeowner about the dogs health , medication etc)
Trusted HouseSitters don’t routinely read reviews . However when a dispute is raised Trusted House Sitters will investigate and take appropriate action against members who break the T&Cs .
This is what another sitter did in a similar situation to you and as a result of an investigation the homeowner was removed from the platform also their inaccurate review of the sitter was removed.
You can read about the other sitters experience on this thread
Are you a Premium member? If the sit was curtailed because the homeowners came home early or in some cases because their listing was misleading then you may be able to claim back your alternative accommodation costs - did member services advise you about this ?
