I've had this service since August, I've had a few successful hits from it but yes the people are less responsive than let's say Roomster.
My main complaint is that every time I relist my room it downgrades my rent price. I put $800-$899 and roommiematch decides to put it down to $600-$699. No customer service. No one will fix it. They claim you can just update your info by refilling out the form but I've found this to be untrue as they took none of my changes.
Seriously what kind of service is this if THEY decide what your rent is?
