You should be able to do a free relist - Stick it on a normal auction (NO reserve )at £1950 and Bobs your auntie.
I would recommend a straight classified ad but I don’t think you can change to classified without paying an extra £15.
Oh and another point - why not stick your mobile number on the ad too - the idea being that if you make yourself more reachable you are more likely to connect and thus sell to someone. Make the process easy for the buyer so they don’t have to jump through hoops to get to you .After all why would you not want to talk to a prospective buyer?
A lot of people get hung up about having their phone number on an ad - I don’t know what they are afraid of…heavy breathing texts??? Before internet that’s how adverts worked!
Soon as it’s sold update ad deleteing your number - easy!
Your choice Claire - but I would go fro the straight auction
